So you double Smith (2 Players) then put 8-9 guys in the box? That totals 10-11 players.
That leaves our other receiver with either single coverage and no safety over the top or literally no one covering him.
You sir would be a bad DC.
(I'm still trying to figure out what Steve's stats from last game tell you/me. I was pointing out you can't say all rookies AND Steve Smith because it makes your statement sound dumb. Usually it's one rookie and SS)
8-9 in the box means how the defense looks before the snap. After the snap, they don't stand still in the same spot. The linemen still either pressure the QB or stop the O line from blocking the second level. The linebackers still blitz, spy or fall back into coverage. The DBs still cover their zones/receivers.
I don't know why you're saying he'd be a bad DC. Its called disguising the play.
To beat the Panthers with Clausen starting... just show up.
