Yup, best to judge a quarterback after his first full season of play. Unfortunately, many of Rex's flaws are not ones that are easily corrected, IMO. He has little poise under pressure, throws off his back foot too much, has poor pocket awareness, and seems to have an obstinate attitude regarding his flaws. Personally, I have always been very patient when it comes to developing players, like Corey Patterson, for example. But I see little in Rex Grossman that inspires confidence that he will develop into anything other than a league average QB, at best. And given his set of flaws, I think that would take 2-3 years to achieve. The Bears' overall talent level puts them in a position to win again next year, and perhaps the next, but the window will not be open forever. If I am Angelo, I move to add some stability to the offense. He's a free agent after next season, I don't see the need to do anything now to replace him.
