I'm trying to think optimistic. While Ed Dickson is strictly a receiving TE, he is very good at just that. Dickson does one thing that Heap never really did, he breaks tackles. His biggest play (against the saints
http://youtu.be/4nAFRt85RG4) was an example of this.
Do I think he will make as much of an impact as Todd Heap? Not really. But that could be a good thing, as Flacco liked to rely a lot on Mason, Heap and Rice. Now coming into 2011, he only has one of those weapons and now he has to spread the ball more.
I think Ozzie is trying to make us a more explosive offense. Does Dickson do that more then Heap? Can't really tell at this point, but with Heap constantly being injury plagued the Dickson change had to be made sooner or later.

As for the Chris Carr/Josh Wilson debate, I'm a little torn. Chris Carr is great on run defense and pretty decent pass defense corner. However, Carr is a nickle corner, nothing more, nothing less. Josh Wilson was a good #2 and decent #1.
No matter what happens this year, injury or not Chris Carr will remain in the nickle, while Foxworth, Jimmy, and Webby rotate the 1 and 2. So we have that position locked up. The top teams are to reliant on slot receivers (Pitt,NE, Indy), so this move was the better move. But I would have wanted to see Wilson return as well.
