Essentially the only guys in position to transfer were Carlton , Polley.
Vital had two years invested , he would have gone only if forced or if Adams left .
Whaley was also a possible but probably by taking a step down,
Adams could have declared but he had a wrist injury which would have hurt his stock. I think that and the Hurley hire sealed him returning
No question the hire was critical. A lesser one and losing
Carlton, Polley, Adams, Vital, in addition to Larrier and the three recruits and the future would look extremely bleak.
