Sky Steele looks at 3 possible DT FA signings, a good show. I'll link it here for ya to watch but of these 3 who would you like?
Raekwon Davis
A'Shawn Robinson
Daquan Jones
Keep in mind they likely will not be spending what it takes to get a Chris Jones or DJ Reader.
I like A'Shawn. Had a career year last year with Giants. Davis is interesting too at 26, if he comes in gets coached up and shows out he could be a good longer piece addition to the rotation.
I wanted Robinson to be drafted by Dallas. Over the last 3 years he's averaged about 60 tackles. Has only about 1 sack per year but has had 5 forced fumbles over his 8 years, not bad.
Davis looks to be a classic underachiever. Poor stats, even for a NT. Also, he's 6-6 (per his NFL draft profile, 6-7 per PFR), that's too tall for a DT. and a 5.12 forty is obviously not near fast enough for DE. 4 years in the league, to me he's a bust, and the Cowboys don't have the luxury of taking a "maybe we can turn him around" player.
Jones is 32. HIs stats are mediocre, does average a bit over 1 sack a year, but not really that much better than Robinson. Less tackles per year than Hankins, though.
If it was up to me, providing the Cowboys can pay it, I'd go with Robinson, to get the consistent tackling and the bit younger age than either of the other 2 above, and Hankins as well. But he may want too much $$, in which case I'd just stick with Hankins if he'll sign reasonably. IF Mazi can improve, Hankins can go to backup/parttime, and he's already familiar with the scheme and the other players.
Just don't see he's worse enough, if at all, than the 3 above to justify paying more money and taking a risk on a new player..
