YOTC did say that 'it's not like he's lost the entire playing group, or anything that dramatic.........'
And, with all respect to YOTC, it's a rumbling that is yet to be verified.
It makes a lot of sense that players would be unhappy with him.
Whether he's lost the entire playing group or not, it generally doesn't bode well when you get factions forming and dissent growing. The lack of cohesion starts manifesting itself on the field and the coach inevitably gets sacked. I have little doubt that renewing his contract at this point would be a mistake. There could be a lot of players heading for the doors at the end of next year if he remains at the helm.
