I'd like to see them add a vet corner, though I think I'd sign a NT first. But yeah it would be welcome.
That aside there are benefits to the kids back there in a secondary, the biggest one being discipline and playing the call. For example we don't know what the calls were so cannot say for sure on these things, but when you have a grizzled vet like Ramsey out there wearing different colored socks and blaming teammates whenever he's associated with any sort of failure I think there's a good chance he's not playing the call and the technique they schemed up for the opponent on 100% of the snaps. I suspect he was quite the freelancer, and that's even with the fact Morris probably had loose reigns on him as well and allowed it to some extent. Same with Hill, who has always been a freelancer or bonehead or whatever you want to call it, where one play he's in position and looks great and then the next he looks like Toast Patterson.
Also last year we had Kendrick struggling quite a bit out there. Did he play the call and correct technique with discipline probably not and likely due to learning in year one.
My biggest concern is they're gonna try to play Kendrick outside again. But let's say they put him in the slot. Durant & Tomlinson outside. Now you have two young corners out there who seem to me much more likely to be disciplined in that call & technique side of things. You won't have one guy running free due to lack of discipline rather it will be when they get beat, which will happen but hopefully a lot less often than it has been happening the past couple seasons. Could be that Tomlinson induces error there being in year one, but he seems locked in to me mentally, so we'll see on that one.
Either way I don't want to get into a Morris thing here but I don't think he was set up for success in that regard. Some of that is on him btw, not absolving him or anything since discipline of your defense is squarely a DC responsibility. But he also had a LB coach under him running his secondary. And the bigger point is these young corners might do quite well in certain ways, with the big one being lining up where they are expected to be and playing the right techniques to funnel the action correctly per the call.
