Not to be a downer, either, but it's good to have Drake insurance. We all thought Mac looked like he would probably be "the guy" for the Pats long-term after 2021 even if the end of the season did fizzle slightly. Obviously that went downhill fast. I don't think we SHOULD be overly concerned about Drake fading too, but in the remote chance that happens, it's pretty nice to have a QB like Milton chilling there just in case, yeah?
If it's year 3, Drake's proven himself, and he's looking at his big contract extension - then you can start thinking about moving Milton, if offers are still good.
