Here's what I do know, as Reich becomes the Indianapolis Colts coach: He has the potential to be a good fit.
Indianapolis agreed to a five-year contract with Frank Reich, making him the team's head coach after he spent the last two seasons as the offensive coordinator of the Philadelphia Eagles, per NFL Network's Mike Garafolo.
Reich, then, has familiarity with the Colts organization, which perhaps was considered a positive since McDaniels ultimately never became comfortable enough to make the move.
If Reich does get the job, however, the pressure will certainly be on the Eagles - and Pederson - to make sure the offense doesn't take a step back next season with two of their key offensive coaches potentially gone. Pairing Reich with Andrew Luck could make for a unsafe combination, leading the offense to return to its previous level of success. Reich is coming off of an impressive Super Bowl victory in which his offense scored 41 points with a backup quarterback.
If Reich leaves as expected, Pederson likely would consider promoting running backs coach Duce Staley to offensive coordinator. Reich was Peyton Manning's quarterbacks coach in 2009 and '10 before coaching Reggie Wayne and the rest of the receivers in 2011. However, Frazier was an assistant coach for the Colts during the 2005-2006 season in which the Colts won the super bowl. He ascended to quarterbacks and wide receivers coach before leaving Indianapolis in 2012.
After being one of the best-ever backup QBs for the Bills behind Jim Kelly, Reich has built his second National Football League career in his own right.
Reich could be the flawless head coach to best understand how to use Andrew Luck.
