Only 4 of the 20 would even be close to the 10th % or below it. What's interesting is that those 4 are top 10 Cs.
I don't agree. You didn't give us numbers for most of the guys. You just claimed they were good athletes. I posted a number of these guys. Their numbers were pretty weak.
A good chunk of the top 15 Centers in the NFL (likely over half) would qualify as below average to bad athletes. Sparq is pretty useless for Centers.
Its not an end all be all, but its something to think about. I would be upset forcing a position and drafting a horrible athlete in rounds 2-3 when there are going to be great players from other positions. I wouldn't really argue with Roullier in round 5, but lesser athletes have a harder hill to climb.
I would be disappointed if we forced a position in any round, but Sparq doesn't factor into that. As I demonstrated, it has no predictive power for Centers. In fact, it's possible there's more of a negative correlation than positive correlation.(would need to have a full data-set to test that)
Lesser athletes don't appear to have a problem playing Center.
Travis Frederick is insanely strong and it makes up for his athleticism. When he gets his hands on a player its over, his hands are like vice grips. The only C I see that with this year is Orlosky, and its not close to Frederick's strength.
Orlosky isn't that strong. I'm not a fan of his. He looks like a guy to me. I'd say that Roullier and Elfelin are the two strongest Centers in this class. Elfelin has other issues.
Regardless, I don't agree that Frederick's strength makes up for his athleticism because I wouldn't regard him as insanely strong. He's a strong guy, but I wouldn't call him one of the strongest OLs in the NFL. Like the other top Centers, Frederick is great because he combines polished footwork and hand usage with a high football IQ, a great understanding of angles/position, and a strong lower body. Playing Center is more about mental acuity, technical skill, lower body strength, and body control/balance/flexibility than anything else.
Athleticism just isn't that important at Center. It's a benefit to have, but if a Center doesn't have the other things I mentioned, he's not going to be good at his job. In fact, despite Kelce being an exceptional athlete, his level of play has really dropped off in recent years because he's scheme-limited due to his lack of lower body power.
