Wilson is a very solid nickle. It would be a mistake to send him packing.
Milliner overcame missing all of training camp and time early in the year. I was going to give him until next year to accomplish what he's managed the last two weeks. Is he Revis? No. Will he be Revis? I don't know. I do know he's going to be very, very good.
As for Cromartie, from all the things I've seen, surgery has been recommended to fix what's wrong. As long as that goes well, he should be significantly better. If we get Milliner a bit improved next year, plus Cromartie back to Revis-counterpart-level at a team-friendly number, that's going to significantly upgrade the secondary. If Allen continues to impress that's another spot we've already addressed. Reed should come back on the vet minimum to add depth/mentoring. The secondary could be very good with a healthy Cromartie returning.
