I don't see Adams as Sterling II as some apparently do, but I also see potential, and it has nothing to do with college production, which I agree is a poor barometer.
James Jones - from and played Tomato Can State, 6'1" 208, 35" vertical, 4.59 40, 22 bench reps
Davante Adams - from and played Tomato Can State, 6'1" 212, 39.5" vertical, and 4.5mid 40, 14 bench reps
Edgar Bennett said one of the things they liked were his hands and able to get the ball.
Adams may not be a YAC guy, but Jones wasn't really except for the fact that he was strong and could shake some tackles. The measurables appear to be similar to James, and if his hands are at least as good, then the potential is there for him to be a good asset. The team has guys like Cobb, Jordy, and maybe even Janis who could be your YAC guys, so having another Boykin/Jones possession type isn't a bad thing to have, especially with us questionably thin at TE.
I didn't really care for their other day 1-2 moves, but Adams I see as a reasonable option.
