A few weeks can make an enormous difference. The NBA originally envisioned its transaction window as an insurance policy. Teams could restock their benches with a few extra players, but fundamentally, their outlooks weren't supposed to change. 

And then, Kyrie Irving led a push to reconsider resuming the season in the Orlando bubble in the name of depriving fans of a potential distraction while social justice reform has so much momentum. Dwight Howard agrees with him. A number of players started testing positive for COVID-19, and Florida's numbers are skyrocketing. In the end, quite a few significant rotation players opted out, including Avery Bradley, DeAndre Jordan and Davis Bertans.

Where once teams might have viewed the transaction window as a chance to fortify a roster leak or two, many will now be forced to reconstruct their entire rotations. If key players opt out of Disney, the free agents that are currently available might have to play real postseason minutes for teams they weren't even a part of before this pandemic. 

The lottery ticket

Look, anyone who's made it to this point without finding a team is a free agent for a reason. This is not peak DeMarcus Cousins. It might not even be the compromised version we saw in Golden State a year ago. Less than a year will have passed between Cousins tearing his ACL and the beginning of games at the end of July, so even if he decides to play, there's no telling how healthy he will be. And even if he can play, his fitness probably isn't ideal. With only eight seeding games, there isn't exactly much time for him to get back up to speed. 

But how often are 29-year-old four-time All-Stars available in the lead-up to the playoffs? Any team that has a roster spot it doesn't know what to do with would be doing itself a disservice by not at least considering Cousins. He's a lottery ticket. His defensive flaws are going to be so great that he probably won't be able to contribute, but on occasion, he might just be able to do what he did for the Warriors in Game 2 of the 2019 NBA Finals. An 11-point, 10-rebound, 6-assist performance can swing a Finals game, and Cousins is the only player available capable of doing that. 

With Howard potentially sitting out and JaVale McGee a coronavirus risk thanks to his preexisting asthma, all eyes will turn to the Lakers. If they decide to bring in another center, Cousins makes by far the most sense. He spent the entire season on their sideline, and has experience playing alongside multiple current Lakers, including Anthony Davis

If the Lakers pass, his intel from spending the season in their walls could be valuable for someone else. The Clippers gave Joakim Noah a 10-day contract just before the shutdown. Would Noah's contributions really outweigh everything Cousins could tell the Clippers about the Lakers? They may not be desperate enough to go down that path, but someone could be. For now, Cousins is still weighing his options, according to his agent

The professional scorer

There is an important distinction to be made. Johnson was waived by the Detroit Pistons on Oct. 21, one day before the season began. He did not play in the NBA during the 2018-19 season. However, Bobby Marks and Adrian Wojnarowski's report for ESPN suggests that players will be eligible to join new teams if they were on training camp rosters, which would make Johnson eligible. However, without a finalized deal, the possibility that such a caveat is ultimately limited to players who were on rosters during the season still exists. The devil will be in the details for Johnson. 

Johnson hasn't played in the NBA since the 2017-18 season, but that doesn't mean he's been idle. He was named the MVP of the BIG3 after leading the Triplets to a championship in his debut season. There is no telling what condition he is in at the age of 38, but Johnson acquitted himself extraordinarily well the last time he took the professional court. Any team needing bench scoring should look Johnson's way. 

The shooters

  • Ryan Anderson
  • Allen Crabbe
  • Gerald Green

In a world in which every player has fallen out of game shape, shooting theoretically becomes basketball's most valuable commodity. Fortunately, free agency has it in all shapes and sizes. Looking for a wing to space the floor in bench units? Crabbe is a 38.7 percent career 3-point shooter. Need a big to draw rim protectors away from the basket? That's what Ryan Anderson was made for! 

It should be noted that the bigger names here all struggled in their most recent appearances. Crabbe made only 30.3 percent of his  3-point attempts this season. Anderson has made only 22.2 percent across the past two seasons. You might be able to steal a few bench minutes from this group, but nobody here is capable of much more than that. 

The point guard

Given the outsize importance of point guard offense, grabbing a spare ball-handler makes sense for virtually any team with a roster spot. Isaiah Thomas is well past his Brinks truck days, but there were signs of life in Washington. Shooting over 40 percent on 4.7 3-point attempts per game is nothing to sneeze at. Few teams are defensively equipped to protect Thomas, but those that are should consider him as a spark-plug. He isn't his old self, but he isn't the shell of the 2017-18 season either. 

The old guard

  • Pau Gasol
  • Nene

Once upon a time, there would have been a line around the block for Nene or Gasol. That time is long gone, and at this point, it isn't clear if either is healthy enough to play. Gasol is recovering from a stress fracture in his foot, while Nene has been dealing with a hip injury and didn't suit up for a single Houston Rockets game (though, in fairness, the unorthodox structure of his contract didn't exactly help). 

It's been a few years since either has been able to give a team meaningful playoff minutes, but younger teams could benefit from their veteran presence. If the Lakers open up a roster spot for any reason, Gasol has already stated his interest in a potential reunion. 

The defender

While some of the players listed were included largely ceremonially, Shumpert is not only capable of helping teams, but actually did so this season. While his shooting remains troublesome and he's lost enough athleticism to prevent him from contributing much else offensively, he gave the Nets 13 fairly strong defensive games when injuries decimated their backcourt. He's not going to swing a championship, but few teams couldn't use 10-15 minutes of stout wing defense. 

The wildcard

  • Jamal Crawford

Crawford originally appeared ineligible, as he was not on an NBA roster this season, but when the eligibility rules expanded to include last season, his eligibility was confirmed. Crawford scored 51 points in his last NBA game. There is little question that he can still score, but what else he can do on an NBA court is less clear. The Lakers gave J.R. Smith a shot, though, and Crawford appeared to have a bit more left in the tank at last blush, so a team looking for scoring should give Crawford a long look.
