A buddy sent me something that I tried to copy into a thread but couldn't find it. It shows the starting lineups for the Super Bowl teams based on the recruiting rankings of the players. No names just basics:

Offense/Defense both teams:

5 stars- 4
4 stars- 8
3 stars- 16
2 stars- 9
unranked- 7

Both O-lines

5 stars- 0 (yes zero)
4 stars- 1
3 stars- 2
2 stars- 4
unranked- 3

OL/DL is very tough because often times guys are late bloomers who were 270 with no P5 offers so they did not get stars. Then you have the ones who are a 230 pound TE and go to a FCS, D2, or D3 school and end up becoming a legit NFL prospect.

It goes to show that the 2 and 3 stars are where the majority of the NFL talent comes from. It also shows that it is impossible to know for sure when they are in HS so you can't put much stock into recruiting rankings.
