The Panthers may not have a choice but to wait until the season is over if they want someone already employed by another organization. Not unlike coaches, the team has to allow permission to even speak to the guy.
Of course, most personnel people (GMs, player personnel staff) are pretty much not doing anything right now except holding their breath to see if their draft choices and FA signings pan out, thereby ensuring their job security for another year.
That being said, I'm afraid anytime I see someone from Cleveland on the list, only because I don't see anyone from Pittsburgh on the same list- you know, that other team Jerry wants the Panthers to grow up and be like....
Omar Khan is up there, though how possible it is to get him is a question.
Add in that there's more than one guy on there with Steeler experiense - Doug Whaley, for example - or experience with another winning program who's in a different zip code now. Browns GM Tom Heckert is among that group, having been with the Eagles for several years before coming to Cleveland.
A lot to flesh out, honestly. I can tell already that putting these together with something meaningful will be more difficult than the coaching ones were. Still, it's something I enjoy, or I wouldn't do it
