When it comes to winning a national championship in college, the recruiting star system matters. There's a science behind this, but all you actually have to do is look at the past several national title winners and where they finished in recruiting the 3-4 years prior. Five-star and 4-star players dominate these rosters, particularly when it comes to recent champions like Alabama, Ohio State and Florida State.

However, when it comes to winning a Super Bowl or making the Pro Bowl, how prospects rated out of high school or JUCO seems to matter less.

There are a few reasons for this. For one, not every player in the league was around at the time recruiting rankings became a thing, though that number is getting smaller by the year. Two, stars aren't an indicator of performance at the professional level of the game. Ratings are made by evaluators based on the level of a player's talent and how a particular recruit projects as a success playing college football.

And three, the math doesn't favor a high percentage of blue-chip recruits, and it never will.

With the 2017 Pro Bowl rosters being released, it's interesting to see how each player rated coming out of high school or JUCO. The players are placed into categories below based on their rating, from 5-star prospects to ones that weren't rated. 247Sports Composite rankings were used to provide a more complete assessment of the player as a recruit, though this admittedly gets more difficult the further back you go.

So when you really think about it, 35 of the 80 players named to the Pro Bowl (43.8 percent) were rated as either 5-star or 4-star players coming out of high school per the 247Sports Composite, which is an incredibly high hit percentage considering the aforementioned limited number of players that receive such distinctions. Also impressive is that 19 players were rated as 2-star prospects or not rated at all, meaning nearly one-quarter of the players at the top of the league in 2016 brushed off the lack of belief in them by talent evaluators and grinded all the way to NFL greatness.
