Mike Preston: It's very easy to figure out Calvin. Apparently, the Ravens didn't think they were worth taking or valuable enough. With Konz, there were some who said he wasn't' strong enough to play right away, but I probably would have taken him. You are correct, Birk is getting pushed around at times and Gradkowski isn't big enough yet to be a consistent starter. Down the road, though, Gradkowski is going to do well. He is smart and has quick feet which allows him to work into the second level. As for Birk, I have my concerns about him as well but he is a gamer. He is going to play hard until the final whistle, even though that might not be enough at this point of his career.
