As I've aged as a sports fan, I find I'm as interested in the franchise building of a team/program as I am by the team's on-field performance (This is not to minimize my fan hopes for a win, just an acknowledgement that I find the mgmt side interesting in relation to outcomes).
I am trying to consider our current sitrep thru that lens with regards to Collins, his contract, and other program variables. Despite my earlier post that Collins may be released a year too late (in a $$ is no object world I'd cut him now), I think his contract was structured for a three year analysis of coordinators and overall performance. I think Collins was specifically hired to affect recruiting towards a new system with less concern of his actual coaching acumen, which so far leaves room for improvement. I think we move on from our DC as our defense is visibly undisciplined. I think our OC is more likely than not to stay as our QB situation has been a work in progress, so I think he gets one more year to develop his offense. I like Sims over Yates, but wouldn't be surprised to see a new guy overtake Sims in two years if he doesn't improve his field management. I'm undecided on Key as line continuity is a significant variable that has yet to settle out.
With no particular guy(s) in mind, I would look to hire a veteran DC with an established record. I think if both coordinators are replaced, the OC is probably a younger room-to-grow guy and one of the two is likely to be Collins' replacement in waiting with a short leash as early as next year. I've been watching GT football for nearly four decades and attended during the B*** L**** years (sympathy and donations accepted).
GT football will survive the CGC experience. Improved coordinators might cover Collins' shortcomings and just let him focus on the things that are important to him such as branding, recruiting, etc. Collins would then be judged on the team's improvement next year. If the improvements prove insufficient, we move on from Collins, the program is farther along, and the transition to a new coach will be less painful.
