If Milton is going to play 3 years in NFL it will be as a QB. Let's be clear about Edelman, he made the roster as a top punt returner, NOT as a developmental anything.
===============================
As with any 6th or 7th rounder, if Milton doesn't make the team at his position he will be cut, just like the other 90% drafted in the 6th or 7th who don't make a roster. He'll be picked up by someone to be a #3 or he'll be signed to someone's Practice Squad.
Let's be clear. He night beat out Rourke. Personally, I don't expect that to happen. We might get a 6th or 7th for Rourke or Milton in the week before the last pre-season game.
For me, I think that the most likely result will be Milton on out Practice Squad, where he will one of the 3 students in our QB university.

As an ASIDE, I'm fine with the pick. I like the idea of replacing Zappe as the one competing with Rourke for the #3 QB spot (and hopefully #2 in 2025).
