Trade offs.
When you move the pocket, in many cases you cut the Field in Half making it easier for the DBs to jump Routes and intercept passes, using Play Action like naked boots or a waggle to move the Pocket might work, but you gotta use it on 1st & 2 d down when they are expecting the run, once our Center went down, we could no longer run.
The Guy you're slamming - saying he ain't a pocket passer?
With 50 secs left after having a bad game, he was able to be mentally strong enough to flush that, and came out with 2 explosion pass plays that were nullified by a low snap and a holding, so IMO he's a good enough pocket passer right now that is working to improve.
Dude never quits, is a gamer and has the clutch gene, I'll take it at this point.
