I think were getting a little carried away, Mcmichael seems to fade away during the year, he also appears to get tired, sloppy, I don't think he's quite the caliber that Gates is. Quite simply Gates is a much better overall TE.
IMO Mcmichael has lapses in concentration, ie, the fumble v New England, and drops many easy passes. He plays with a lot of heart.
Let's forget that it wasn't until 2 years ago that Bree's came around, argueably because of the arrival of Gates, and improvements at the offensive line position.
He looked terrible 3 years ago, he lost his starting job to flutie at 1 point.
So while i think Bree's would be an upgrade, he needs to have a strong offensive line in front of him to do so. He is an improvement over what we have. So if we are going to nab him this year, I expect to see us go after a OL in the 1st round, probably LT.
