Beyond his pristine arm talent -- he led the NFL with 40 touchdown strikes -- the Colts quarterback has proven to be one of the league's most elusive movers in the pocket.
We saw that on Luck's 8-yard touchdown gallop in Sunday's Divisional Round win against the Broncos. The score was called back by penalty, but it serves as yet another example of how much trouble he can generate with his feet. Denver finished with zero sacks on the day despite having their hands on Luck plenty of times.
"I mean, he's a lot faster than Roethlisberger, much more a threat to gain more yardage and gain it quicker," Belichick said, adding: "... He can run, but if extends the play, then he has the ability to create big plays, and we've seen him do that multiple times throughout his career already."
Of all the four remaining teams, the Colts are the most incomplete across the board. But with Luck operating at such sterling levels in January, anything feels possible.
