as far as concerns are with the cowboys, i'm concerned about the lack of depth at the wide receiver position. other than terrell owens, there's not much. if terry glenn is healthy, then i'm not worried. but as of now, i don't trust patrick crayton as the cowboys #2 receiver. i don't understand all the bullshit the cowboys coaches are saying about him having the best hands on the team. plus, the younger receivers like sam hurd, miles austin and isaiah stanback should step up soon if terry glenn won't be able to play.
as far as expectations go, i don't see the cowboys' offense missing a beat. if anything, they should be better because tony romo has new weapons with rookie rbs felix jones who finally gives the cowboys a homerun threat, and tashard choice, an underrated player who i think was a steal for the cowboys. he's a good back in between the tackles, and he should provide adequate depth behind marion barber. rookie tight end martellus bennett from texas a&m is a pretty good receiver, and will help the cowboys as soon as he polishes his blocking skills.
on defense, i think defensive end chris canty is a player who could have a breakout year, after having a solid season last year. tank johnson says he's more comfortable and finally has a grasp of the defense, so he should provide nice depth at nose tackle behind jeremiah ratliff. with zach thomas coming to the cowboys, i expect to see him to get his teammates in position to make plays. with demarcus ware, greg ellis, and anhony spencer providing a pass rush, i could see the newly upgraded and finally healthy secondary taking advantage of this.
