I like Fernado Mendoza, with a big and accurate arm, with just enough Mobility, and athleticism to create opportunities outside the pocket, who fits the classic NFL QB profile: 6' 5 225 lbs.
I saw a recent McShay podcast where him and his buddy compared Mendoza to Goff. Saying that is his ceiling....which they both agreed was a good thing. After watching him today vs Oregon, I can see that comp. Tall kid, not super mobile, but a decent athlete, and very accurate.
If Stafford retires, then I could see the Rams trying to move up for a QB who they think could be ready by 27' (Jimmy for a year maybe) One positive is, none of these guys are a slam dunk, so it might make it easier to pull off a trade. Kind of like when Goff came out. A very good prospect, but not a guy who teams were drooling over. So he was gettable. Mendoza, Matteer, Moore, Sellers, all have some question marks. So if they ID one as a guy they really like, they would have a good shot to go get that guy if they want to.
Plus, if Stafford retirees, they could decide it's a reset year so they can throw a few picks at a trade as you are not looking at instant impact in a reset year.
If Stafford comes back, then maybe you go with a mid round prospect and just see if you can develop a guy before going into the 27' draft. Then use your top 3 picks for instant impact to support Stafford for one more year.
