Then you remember falsely because that drop did NOT kill the Pats. The drop that Caldwell had was against San Diego in the Divisional round and the Pats still won that game. In the AFCCG against the Colts, Caldwall was mauled in the endzone and a flag should have been thrown and it wasn't. Not to mention that the defense couldn't keep the Colts from scoring.
It's amazing how people try and change history ..
No, you're wrong. Go to: New England Patriots vs. Indianapolis Colts - Play By Play - January 21, 2007 - ESPN
The Pats had 3rd and 7 on Indy's 10 with 7:50 on the clock, with the score tied at 28. Brady threw to the right to a wide open Caldwell who dropped the ball. On 4th down they kicked the FG that put them up 31-28.
Not saying there wasn't a PI call in the Colt game as well. But Caldwell definitely had a HUGE drop in the AFCCG.
