Sam has been impressive. It looks obvious to me why he was SEC Defensive Player of the Year. I think people actually trivializing what he has been doing because of the gay thing, saying, "oh..it is only 1 sack..blah blah blah" but when you watch him during the games, he is pretty tenacious, has an explosive first steps, and uses his arms well. He's better than a 7th round pick, that's for sure. 3 sacks during the preseason, a few QB pressures; and he's disruptive .
If the Rams cut him, he'll be signed relatively quickly by another team. No way will they be able to stash him on the practice squad.
