Oh yay, the vax argument again...
Anyway, this team is not better without Chase / Sweat. They may be "fine" without them depending on the opponent, but definitely not better. I wouldn't trade either one at this point. You're not getting a ham sandwich for Chase at this point anyway, and Sweat is easily the best player on the D right now (besides Jonathan Allen). It would be dumb to consider trading either one of them right now.
