I know that I will get bashed for this and get sarcastic responses, but Wes going to Denver is the best thing to happen to Tom. Think about this, before Wes came to New England, Tom's favorite target was the open target on the footbal field. When Wes came along and was productive right a way for 6 years, he relied on Wes a lot and really handicapped the offense in a way. Tom would throw the football to Wes with 3 guys surrounding him when there were others that were possibly open. When you rely on one particular player so much, it will hamper the offense. This transaction will benefit Tom & the offense. Though its hard for a lot of fans to believe that, all you need to know is that they had success before Wes came along and they'll have success with Wes in Denver.
Look what happened when the 49ers went from Joe Montana to Steve Young back in the early 90's, they still had a lot of success without Joe Montana.
