There are so many viable options out there, but here's links to bios of the three names as a follow up to an earlier post I made.
Joe Conlin Yale OC profile - came up under Chip Kelly at UNH, in a year has turned Yale's offense into a top 10 FCS unit, has NE ties
Brian Scott ODU OC profile - all they do is score TD's and crank out yards, has NE ties (Maine grad)
Ryan Carty UNH OC profile - NE ties, track record of coordinating productive offenses, recruits N. NJ and parts of MA.
Also, Jagodzinski is now the Offensive Coordinator at Georgia State, transitioning them from start up to FBS. That guy could coordinate an offense.
I know many want the s e xy hire, a name guy form a name FBS/BCS/P5 program, etc, etc.... Me, I'll take a proven record of leading offenses that can move the ball and score points. What's more impressive is more often than not the three teams above are doing it with talent deficits compared to their opponants (from a speed/skill/rating pov), and still cranking yards and points.
