That's the rub. Mental processing isnt just a stat to go off, and can be developed in the NFL provided the kid isnt rushed in to a bad situation.
The Rams wont be drafting in the top 5-10 picks and trading to get there from late 20's is a pipe dream. So where's Stafford replacement coming from? Doubt they'll be in position to pull off another Stafford miracle.
As for the Purdy question, fuck him and that whole organization. That said, McVay doesnt lose like Shanny does. They win a SB with a mid round QB who they "developed" then heck yeah I pay that guy 55 mill.
They drafted Bennett to be a John Wolford backup, if they draft a QB its to see if they can make a Montana (Fuck Purdy and Brady)
