Reich, 56, emerged as the favorite for the job after meeting with Colts general manager Chris Ballard on Friday. "I look forward to working with Frank to deliver a championship-caliber team to the city of Indianapolis".
The loss of Reich and DeFilippo would leave the Eagles in need of both an offensive coordinator and quarterback coach. The Colts seemingly wanted an offensive-minded coach when they were attempting to hire Josh McDaniels.
Reich, who didn't call plays with the Eagles, began his coaching career as an offensive staff assistant with former Colts coach Jim Caldwell in 2008 after having retired from playing 10 years earlier.
There's no question Reich has helped develop quarterbacks on a variety of levels with the Chargers and Eagles.
What they're certainly considering doing first is promoting running backs coach Duce Staley to offensive coordinator and wide receivers coach Mike Groh to quarterbacks coach.
Fortunately for Indianapolis, it didn't take too long before they found their man. Reich is most known for leading the Bills in the "The Comeback" game, a 41-38 overtime victory over the Oilers in AFC wild-card playoff game. As a college player, he led Maryland back from a 31-0 deficit to beat Miami 42-40 in 1984. Numerous play calls were created to get the ball out of Foles' hands quickly in order to beat the pass rush, something that Andrew Luck would benefit from. Or, since Polian once called Reich the "greatest backup quarterback in National Football League history", he'll know how to deal with the possibility of no Luck, too.
Reich wasn't the Colts' first choice. That's anyone's guess, but his integrity and background make it easy to support the Colts' decision to find out.
