Sure, certain guys come in top ranked and become stars, but because football has such big rosters and so many positions compared to Bball there is a lot more room for diamonds in the rough.

A 2nd big factor is kids at 16 and 17 are being ranked and by the time they are 22 or 23 have a totally different body physique. You can look at pretty much any past year's rankings and be like who the fuck is that? about many of the top 50 players.

Perfect relevent example right now, Joe Flacco was an unranked 3 star QB who committed to Pitt then transferred to Delaware because he wasn't getting any time behind the highly ranked Tyler Palko at Pitt.
