Rapid Reaction: Colts 21, Raiders 17

INDIANAPOLIS -- A quick few thoughts on what happened in the season opener at Lucas Oil Stadium:

What it means: Indianapolis Colts quarterback Andrew Luck picked up his eighth come-from-behind victory when the middle of the field looked like a wide-open freeway and he took off from 19 yards out to put his team up 21-17 in the fourth quarter. Luck led the Colts on seven come-from-behind victories last season as a rookie. The Colts, however, had no answer for Oakland Raiders quarterback Terrelle Pryor. Pryor ran for 112 yards and threw for another 217. Pryor tried to top Luck, but safety Antoine Bethea picked him off at the 6-yard line in the final seconds of the game. Greg Toler intercepted Pryor in the end zone in the first quarter.

Stock watch: The Colts looked like they were going to have a field day against an Oakland defense that had nine new starters. Luck started 11-of-11 and the offensive line was doing its job by protecting its franchise quarterback. But then things changed. The offensive line resorted back to last season’s line and Luck was sacked four times. The offensive line would have been the reason behind the loss if not for Luck’s late touchdown. Luck was sacked 41 times last season.

Foot problems again: Colts tight end Dwayne Allen, who told ESPN.com he was one of the best tight ends in the league last week, caught a 20-yard touchdown pass from Luck and then put the football between his legs a couple of times. Allen missed most of the second half after injuring his hip. That’s not good since Allen missed the entire preseason with a foot injury.

What’s next: The Colts host the Miami Dolphins at Lucas Oil Stadium. The Raiders have their home opener against the Jacksonville Jaguars.
