Thanks for this write up.
Sweat is someone I watched for awhile.
Super big dude, but conditioning and motor is a concern for me.
I don't think Rams will go in this direction, but for other teams, you are looking at run stopper that you may not have for goal line/4th down and 1 stances if he had a few snaps before.

He gets pushed pretty badly on stretch plays as his strength mainly is projected forward. And he certainly doesn't have the speed to chase.
At times, I see him giving up thus making it look like the lineman is easily blocking him on stretches.

Interesting prospect where will see if his size/weight and mentality translates well to a professional environment with professional conditioning and routines.
