What exactly are you referring to?Expecting a 31 yo player to suddenly be able do something effectively, which they have never been relied upon to do before in their career... sounds like pure hope. Sure it could happen - but i wouldn't bet on it.
Don't brush it off like it's some kind of trivial responsibility which anyone can learn to do. If it were that easy, then I'm pretty sure someone already on the roster would have picked it up by now & ran with the opportunity.
And where did i say that a potential replacement needed to be an exact clone of Edmunds? I just want(ed) someone either with recently proven NFL ability (not Kirksey) or a prospect with realistic potential to fill the role (again not Kirksey).
If he turns out to be the answer there, then I'll obviously hope he does as well as he can. But don't act like signing him is a foregone conclusion to effectively filling the position, because it isn't. That's akin to watching them sign Jermaine Ifedi then thinking 'Bills finally filled that RT slot, great job Beane'. The only difference is that Kirksey is a name which more people have heard of.
I'm no expert on Kirksey, so I'm just relying on what reporters have said about him:
Texans analyst John Harris in 2022: "He's a leader on this team, wearing the green dot as the communicator between the sideline and the huddle. He has a great way with young players and provides leadership regardless of any situation. . . . What Kirksey gives the Texans that they've lacked for YEARS is the fact that he was such an asset in pass coverage. He had eight passes defensed which was the top total for a player returning to the Texans in 2022. He's vital as a middle of the field player in Tampa 2 coverage but his ability and intellect reading routes and route combinations helps the defense in all facets of pass coverage."
Basically this is my impression of him. A smart, coverage LB that is undersized and probably losing a step at this stage in his career. I look at him as a major upgrade on the Klein role in terms of someone that can raise the floor of the room by being highly intelligent, getting the defense on the right page, and being in the right position. He's getting older so probably doesn't have the speed to be highly effective anymore, and so hopefully Bernard takes the job and runs with it, but similar to the Odefi signing, I see this as a raise the floor move if all else fails.
