Due dilligence? Dolphins have an entire scouting department and personnel team that probably dumped 1000 of hours scouting this kid in 2018.
It really is very simple. Miami saw an opportunity to pick up a talented QB, age 22, for a very late 2nd round pick, that they felt they bring in an attempt to develop for their football team.
There was no better value to be had at that pick. There are no guarantees . . . Roll the dice on the QB.
What happens from there is all on player and coaches, but they did not make the wrong move here in acquiring Rosen for what they gave up for him.
I agree with taking a shot at a qb however it’s highly disappointing that he’s either not being coached up (making same mistakes) or isn’t really all that talented. Either way that’s problematic.
