Floyd isn't going to get tagged with a suspension of more than a game. The reason is because Goodell already set a precedent with malcontent Sheldon Richardson.
Sorry, but falling asleep in your car after drinking is not nearly as bad as driving 143 MPH with a loaded gun in your car and a child in the back seat.
If Goodell tries to suspend Floyd for more than a game, then the NFLPA will fight it because of the precedent already set by the Richardson decision.
As for your comments about the two play-off games, Floyd being active/inactive had nothing to do with how "sloppy" or "polished" the team played.. That's got to be one of the most ridiculous insinuations I've heard..
As for whether or not Floyd is dressed. I wouldn't be surprised to see him dressed and Lengel not. Multi-TE sets could be with Fleming and Bennett.. Floyd is the better receiver than Lengel.
Everything depends on the match-ups that Belichick believes he can create.
