I wouldn't be against Dallas bringing in Matt Jones for a look if he were to be waived by Jax. However, I am not sold that he could beat out Crayton and even if he were to beat out Crayton, I would view that as a battle between #3 WR's who due to circumstances are thrust into a #2 role.
Matt Jones was the #4 WR in Jax last season. #4!!!!! He was behind guys that the Jags thought were not good enough so they went out and upgraded the position with two other so so players. The Jags look at him as well, pardon the pun, JAG (just a guy).
I may be in the minority here but I don't believe that the Cowboys "problem" at the #2 WR has anything to do with being able to "stretch the field". I have said it before and I'll say it again, what made Terry Glenn so good was not just the fact that he had speed but it was the ability to beat man coverage on a CONSISTENT basis. Dallas, IMHO, needs that more than anything because as long as T.O. and Witten are performing like top 5 players at their positions, they will have coverage rolled to them constantly. Meaning, whoever is playing the #2 WR position has to have the ability to beat man coverage consistently in order to be effective.
In the Giants playoff game and in the second half of the season, Crayton was unable to consistently beat man coverage and the offense would stagnate once this occurred.
In regard to Matt Jones, in Jax all he ever saw was man to man coverage with a mix of zone coverages on obvious passing situations. Why? First, because Jax has been and always will be a run first team and Fred Taylor/MJD will get the priority of the opposing teams DC. Second, as I stated before Matt Jones was the 4th WR in Jax so why would any DC roll coverage his way? They wouldn't, thus he got one on one matchups frequently against the other teams Nate Jones CB. Yet, his numbers are not off the charts for '07 (24 rec 317 yds. 13.2 yd/catch 4TD's).
So I am to believe that he would fair better against Anthony Henry, Pacman Jones, Mike Jenkins type CB's (#2 CB's in Dallas but Pac would be a #1 for many teams) just because he is in a Cowboys uni? I don't buy it. As a #2 WR I don't think he is much of an improvement over what Dallas has already in Crayton. In other words, Jones is at best a #3 WR in this league and so is Crayton.
I would give him a shot but wouldn't expect anything more than what Dallas got last year. If he came in and lived up to his draft status and guys like Stash were proven correct, then I'd be as happy as anyone because it would mean the 'Boys were winning games and the move was a success. I just wouldn't bank on it.
