People don't blitz on passing plays all that often in the redzone. It makes much more sense to sit back in a zone and force the QB to throw into a tight window. If he tries to run it, you have people looking at him.
QB's that can move well and put pressure on the defense with their legs and/or arm tend to have a lot of RED ZONE success.
And I disagree that arm strength doesn't have anything to do with it. IMO it has A LOT to do with it. You said it yourself...The windows are smaller. Arm strength becomes more apparent in shorter spaces. Guys with guns can zip balls into tight spaces on a regular basis. Having some mobility also helps because it makes defenders abandon their zones to stop the QB from running.
Schaub doesn't have either one of those attributes going for him and that's why he's never been a really good Red Zone QB.
