With just three weeks left in the regular season, rumors are in overdrive in league circles in regard to possible new head coaches and new general managers. That isn't the most pleasant thing for those on the hot seat to hear, but there's no way around it; there will be change, it's just a matter of how many teams decide to make changes within their personnel departments.

Earlier this season I looked at the most likely candidates to emerge for head-coaching positions. Here is my list of candidates to be in the mix for general manager jobs, broken down by the ones most likely to get jobs and others likely to get strong consideration in the future.

Tier 1

1. Tom Gamble, vice president of player personnel, Philadelphia Eagles The son of former Eagles president Harry Gamble, Tom started his NFL career with the Eagles in 1998. And like his late father, he is a rarity in NFL scouting departments these days: He not only has extensive pro and college scouting experience, but he has experience with contract negations and the salary cap, and he even has coaching experience in his résumé (defensive assistant/quality control coach with the New York Jets for two seasons: 1995-1996). Over the years, several teams have shown interest in him for general manager jobs (most recently last year -- Miami Dolphins and Tampa Bay Buccaneers).

And it's worth noting that Gamble has worked closely with some of the best evaluators in the NFL such as Bill Polian (with Carolina Panthers and Indianapolis Colts) and Trent Baalke (with San Francisco 49ers). And most recently, Gamble has had a hand in the turnarounds with the 49ers and Eagles, where he has worked closely with head coach Chip Kelly.
