Carolina vs New England last play

[zm1283]

I want you guys in the "No DPI" camp on the NE/Carolina play to watch this play starting at the 4:00 mark in the video:

GameDay: Denver Broncos vs. New England Patriots highlights - NFL Videos

The Denver receiver is running a "go" route straight down the field. Talib for NE does hold the receiver, but Manning severely underthrows the ball and there is zero chance the receiver would have caught it. It gets intercepted, but they stick with the holding call.

How is this any different than last week's play? I thought if the ball was underthrown and not catchable by the offensive player and it was intercepted, they "philosophy" was to ignore the defensive penalty. When Talib catches Manning's underthrown pass he is eight yards in front of the receiver who was running the complete opposite direction.

Edit: Go to 5:20 and watch the PI no-call when the Patriots have the ball in OT also. How is that not DPI?
