Robinson used to play football, and recently said on a podcast with Believe the Hype that he thinks if he played in the NFL he'd be elite. Transcription via Ball Don't Lie:
"If I was in the NFL, I'd probably be at least, like, the first or second DB in the NFL. One, two or three, I'd say, because [Tampa Bay Buccaneers cornerback] Darrelle] Revis is pretty solid, [Arizona Cardinals corner] Patrick Peterson is pretty solid and you got my man Sherman holding it down. It'd be a tough position, but the level that I was playing football at at the time, I was — you know, it was fun for me and it came pretty easy. [...] And I only gave it a year in college, so for me, it'd be pretty scary to think about, you know, my future in football. If I really gave it my all, and stopped focusing on basketball, and gave everything I had on football, I'd probably be one of the best corners the NFL has ever seen."
Richard Sherman is 6-3, Peterson 6-1, Revis 5-11. So they've got a litte bit of size on Robinson, but his vertical is likely higher than any of theirs. He's got the upper body muscle to jam receivers and the speed to recover.
So yeah, I think he's got a point here. Robinson isn't the only player who thinks he could handle the gridiron. LeBron James also used to play football and recently said he wants to play in one game someday.
I makes you think it would be worth it when the next lockout comes, and believe me, it's coming, that the players should organize a game. They did some flag football in the last lockout. Why not beef it up to tackle next time?
Oh, that's right, because they're all on incredibly lucrative guaranteed contracts for multiple years that don't require them to suffer the equivalent of a car accident a dozen times in a three hour period.
