Certainly very possible! Though if my chronology is accurate, Dunn was promoted to AHC only 3 days prior to Miss St.'s publicly announced departure of its RB coach to Saban's staff. You know things were going on behind the scenes before then. It seems like plenty of time for Saban to have inquired about, negotiated and signed the MS RB coach. Moorhead was probably on the phone with RE the minute he hung up with Saban ...lol The time line would fit with RE's promotion of Dunn.
The other scenario would suggest that TR was ready to leave because RE took the AHC title away from him. Though timing-wise, everything would seem to have come together in a very conveniently short time for him considering he landed an SEC caliber coaching position with a former coaching buddy of his to boot. Who knows for sure, but TR did a great job for us while here....wish him all the best in his new position!
Here's is the chronology:
2/22/18: Burton Burns steps seem retires as Alabama's RB coach after 11 years.
2/22/18: Joe Pannuzio moved from TE coach to RB coach at Alabama. No experience coaching RBs.
1/16/19: John Dunn promoted and given raise at UConn.
1/21/19 morning: Charles Huff from Miss St hired as Alabama RB coach. Worked 2 years at Penn St. with Moorhead.
1/21/19 afternoon: Terry Richardson rumored to be going to Miss St as RB coach.
1/22/19 morning: Terry Richardson leaves for Miss St as RB coach.
I think Moorhead lost his RB coach and he turned to Richardson who probably got a 50% raise. By the way, Miss St. has the lowest assistant coach salary pool of all of the public SEC universities. Thus, it is hard for Miss St. to hire top P5 assistant coaches.
