With all of the talk regarding issues with Pep Hamilton, I thought it would be prudent to look back at his time as offensive coordinator of the Indianapolis Colts. Below is a link to an article summarizing a few of the main issues that plagued Pep Hamilton's time in Indianapolis, which resulted in his firing during the middle of the 2015 season. While I can't comment to the validity of all the points raised in this article, I found this part to be a bit alarming:
"One person in the organization told ESPN.com had that had been asking Hamilton to play with tempo for more than two weeks but that their suggestions weren't being received."
It goes a bit more into depth into the issue, but it does seem that tempo has never been an area Pep has valued or implemented under previous offenses.
This seems to support the claims that changes need to be made to this offensive staff in order to bring somebody on board who can provide the necessary expertise to incorporate uptempo elements along with a quick strike passing attack.
