This is a pretty strong group. We all have the one of the four that we consider a weakness. However, most of us are fine with our own list of 3 top corners. Absent injury, the 4th needn't get much action. Of course, much depends on game scheme, if the coaches trust that Rowe, Jones, and McCourty are all to be defending on relatively equally.
IMHO, C Jones just isn't worth a roster spot as a developmental CB. There will be camp competition, if only from Practice Squad players and late round draft choices.
Agree 100%.
Going into 2017 Camp, I viewed Gilmore, Butler and Rowe as the clear top three corners. Below them were Coleman (3rd year), Cy Jones (2nd year) and Jon Jones (2nd year).
Coleman had by far the most defensive experience, but also seemed to have hit is (relatively low) developmental ceiling. He also hadn't contributed very much on ST in his two previous seasons. He seemed expendable to me.
Cy Jones had received nearly as many snaps on defense in 2016 ("tryout" more or less) as Coleman, and he wasn't irredeemably horrible. In spite of his yips on returns, he seemed to have the potential to develop into a more complete contributor than Coleman.
Jon Jones seemed to be exclusively a special-teamer (though a very good one).
Coleman ended up being traded at the end of Camp (as I predicted at the time). But Cy Jones tore an ACL and was replaced (more or less) by Bademosi, veteran special-teamer/reserve CB. I expected Jon Jones to remain pretty much STO, but he really took advantage of his opportunities when Rowe was injured (injured again) and appears now to have passed Cy Jones on the CB depth chart by a fairly wide margin.
Cy Jones was dreadful on punt returns (even when he wasn't fumbling them), so he's likely no help in replacing Amendola there. CJ's kick returns (22.5-yd avg) were adequate, but easily surpassed by Dion Lewis, and now upgraded from even further with the acquisition of Patterson (who is also a decent gunner on ST, apparently).
So, at this very early stage of 2018 roster-building, it seems to me likely that Gilmore and Jason McCourty are the top two CBs with Rowe (who contributes almost nothing on ST) very possibly being strongly challenged by Jon Jones (still a high-usage special-teamer) for the third spot.
The Pats will certainly carry five CBs, but unless Cy Jones comes back strong from his injury and shows some hitherto unseen defensive chops (and/or ability to make significant contributions in a non-returner ST role), it seems to me that he may be rather easily knocked off the bottom of the roster by perhaps Ryan Lewis or by someone who's not yet on the roster.
