The Pats start more than 2 WRs usually.. Welker is a slot guy, Moss is a flanker. They typically have another flanker, and the fact I can't even think of who thye play there tells you that Knox would likely take that spot. In IND he'd be as good as Collie or Garcon, maybe better.
I see what MDSkinner said, I just think the Cutler thing is more perception than substance. The Bears have lost games that Cutler's given away. IMO they wouldn't with Orton.
Maybe it's fair to think Orton coudln't make all the throws Cutler could, but he hasn't really been asked to in the NFL. And when he was at Purdue he demonstrated he could when asked. I just think the Bears traded one QB with weaknesses, for another QB with just as many, though a different set, of weakness.
I don't dislike Cutler, he's got a lot of physical tools. I just don't think he was an upgrade over Orton.
