i would also add that goff had similar problems coming out of college and it took him a couple years to start filling out.
And the Rams training staff has their experience with JG to draw on.
If in fact this guy has similar issues.
Here is the draft analysis by a Washington writer from when he was picked.
from https://www.audacy.com/thefandc/sports/washington-commanders/snider-commanders-reach-emmanuel-forbes-no-16-nfl-draft
Forbes is a ballhawk with six pick-6s last year. He intercepted 14 passes at Mississippi State. Forbes was durable over three seasons, tackles well and runs fast. Who doesn’t want a corner with those traits?
If Forbes was 186 pounds, it would be a solid pick. But, he’s not and that leaves some doubt. The NFL is a big-boy league and 17 games wear players down. That last month is played on grit and duct tape. Players are often down 5 to 10 pounds from the season’s start.
Surely, Washington will put Forbes on a special diet with supplements to bulk him up the best he can. But, Forbes is just naturally skinny
