The facts are that the team Regier built didn't work out as intended. Buffalo now has (one of?) the youngest teams in the league and 8 top 60 picks in the next two drafts.
Either you believe in Regier and lets him rebuild the team or you bring in someone new now and let him rebuild the team. If you keep Regier and he fails it will be much harder for a new GM to come in and right the ship
Is the lack of success because of the roster or how they were used? I'm of the belief that Ruff was the problem, that when Darcy brought in skilled players they were put into situations that didn't suit them. Taking offense minded Myers and making him Rivet, making Ehrhoff into Shannon. Putting Afinogenov on the 3rd line, trying Leino and Grigorenko in Guastad's role, trying to make Vanek into Dixon Ward and Pominville into Varada.
Ruff's recent comment about wanting to be a coach/g.m. implies he had a different vision of a team than Darcy. Maybe he wanted a team of 3rd liners and no skill.
I would prefer Darcy gets more of a chance to perform than the past 27 months, after years of not having a budget for scouting, free agents (or possibly a coaching change) he finally does. He has made good trades the last 2 seasons, good free agent signings and has loaded up with prospects.
It's impossible for me to blame Darcy after he added Hodgson, Ehrhoff and Leino to a playoff team and the team subsequently got worse. Just not sure if he is being judged fairly given the circumstances surrounding his tenure.
*edit* I'm not saying Darcy is blameless or untouchable, would like Dale Tallon as g.m. actually
