Yard-wise, yes, but not completed "downfield" passes.
ALL of Brady's completions, as far as I can tell, were short passes...EXCEPT the one to Vereen in the first quarter...and the 22-yarder in 2nd half to Edelman down the middle.
But once you're up, you don't even need to throw downfield, do you?
If you review ALL of the 2nd-half pass plays, as I have in Espn's play-by-play account, you'll see any double-digit gains in 2nd half were ALL (except 1 by Edelman) short passes. Quite significant YAC (Yards After Catch) kicked in on 3 other passes:
* 16-yarder by Gronk (was a "short" pass)
* 16-yard TD by eligible lineman (you can see this one online somewhere)
* 23-yarder by Edelman on wide-out screen
So we're back to confidence-level issues: Teams are going to pass, no matter what the weather conditions are. They are more likely to throw it short in wetter conditions, and especially when ahead.
Indy didn't have that luxury once falling behind by multiple scores...and Luck is probably #2 Q in league behind the Ravens' QB in throwing downfield as a regular part of offense...so you could see reluctance to move away from that because that success is what got them where they were.
Are you serious? Indy didn't have the "luxury" of throwing short yardage passes because they were down 10 points with more than a half of football left to play? Your entire "argument" on this point is based on the absurd notion that an NFL team would go into desperation mode and start heaving the ball downfield in the second quarter because they're down 10 points. Nonsense.
