A quarterback and a center spend a lot of time really, really close together. It's an intimate relationship, and as such, both parties need to have a certain comfort level.
Aaron Rodgers, in an interview with Cabbie Richards on TSN Radio, shared that he likes his centers like he likes his martinis: dry and at an easily accessible height. Some snippets, via Sports Radio Interviews (you can listen to it here):
"There's two main components that a center needs to have, and it's not quickness or agility or snapping or anything. It's two things: One, he has to have a good height, and I'm talking about where his butt rests. It can't be too low because I don't wanna get deep in that stance and it can't be too high so I feel like I'm standing up. It's gotta be just right. He's got that.
"It's a feel. My center in college was about my height and he's real low in his stance. So it made me have to kinda duck down a little bit. It's hard to get out of center. Scott Wells — my previous center — [and] Jeff Saturday: great height. Great butt height."
And yet, that's never something they measure at the combine. I think they should, if only because it would be great to have a chance to interview the guy who has to measure butt height all day long.
So what's the second part of the equation, quarterback?
"And the second is most important, and that's sweating. How much do they sweat? The worst thing that you can have is third, fourth quarter on a October day where it's 65, 70 degrees and he's sweating through his pants. Because that is not a situation you wanna be in. You gotta change pants at halftime.
"Our backup center — great guy — Evan Dietrich-Smith, he has major sweat issues. And when you get that ball snapped up and there's a lot of sweat that just splashes all over you and on your hands and the ball — it's not a good situation. So he actually has changed at halftime before. So those are the two things you look for: butt height and sweating. Jeff's doing really well in both categories. … Low sweat ratio and solid butt height."
Poor Evan Dietrich-Smith. That's probably not something he wanted the whole world to know, and also, he may never become a starting center in the league with the waterfall of perspiration coming from his hindquarters. I wonder if he's thought about making the switch to guard.
