Drafting Brady first round is crazy

Why does everyone just assume Brady will be back to '07 form this year? Wishful thinking? It is CRAZY to draft him as high as his ADP and especially if Brees is still on the board. He hasn't played football in a year and a half. He's 32 years old. Physically he has likely lost a step. Mentally he has likely lost a step. Did anyone see Manning in his first few games coming off knee surgery? He looked like he was playing scared. I expect the same from Brady. Football is a young man's game and even pretty-boy-Brady ages like the rest of us. Moss is 32, Galloway is 38, Fred Taylor is 33. I don't see another year even close to '07. I'm not saying Brady won't have a good year....maybe even great....I'm just sayin I don't want to make assumptions in Round 1.
