To my knowledge, Skins have signed Cofield and now Bowen. No word on any signing for Jenkins, just that they were pursuing him. My guess is that the money in a bidding war with Dallas got to the point that they decided to take Bowen and let Dallas have Jenkins for slightly more money. We'll see.
As for Bowen, good for him. I would have liked to see him stay, but that's too much for what he's shown on the field, IMHO. Give me Jenkins and then a lower cost veteran DE like Coleman or Smith formerly of the Browns. Neither of them really excites me, but playing in a rotation and knowing Ryan's scheme would likely be enough to get the job done. Would still mean Lissemore or one of the other young guys is going to have to step up, but it's time for that to happen.
Another interesting possibility is that they could look to sign Jenkins and re-sign Spears. I haven't heard what Spears is looking for at all, but if you go that route, you can bump Igor off the starting line-up and bring him in as a rotation guy. If something does happen to Jenkins injury-wise, you've got someone to plug in for the short-term. It would also lock up the starters for a few years to yet a younger guy develop, and allow you to either cut or let Igor walk next year.
