"I'll definitely be very excited about the opportunity regardless of who we're playing," Jackson said. "Obviously me coming from the Eagles, that will definitely be emotional and a big game, but I like to say every game will be the same.

When he arrives, he'll be part of an offense that includes proven receiver Pierre Garcon, promising tight end Jordan Reed and another new receiver in Andre Roberts. Not to mention running back Alfred Morris.
It could land him in another offense that, after Philadelphia, is explosive.
"The biggest thing for this move is finding a place where I can be happy and go out and be myself," Jackson said, "and here was the best fit for that, so I'm very excited."
