Playing center is one of the most cerebral jobs in the NFL. There's a lot of mental chess being played, a lot of scheme, communication, understanding, comprehension and mental execution that needs to go on to get the whole o-line playing right.
Over the past four games there was a big drop off from 15 year pro Harvard Graduate Pro Bowler top 3 center Matt Birk, and 2nd year pro from D-II Delaware Gino Gradkowski. I think Matt Birk was criminally underrated even during his time here in Baltimore. The guys at Pro Football Focus ranked him in the top 3 each year during his duration here in Baltimore, but I'd keep reading posts on this board about how he's "Old man Birk" and how he's lost it, how he's getting pushed around. I didn't think any of this scape-goating was really accurate then, and I feel vindicated now.
Let's twitter-bomb Matt Birk with compliments and begging until he picks up his helmet and gets out of retirement! https://twitter.com/BirkMatt
