It is very early in the season so it is hard to really tell much - TN has a recent record of throwing in some early season clunkers and JMU may be just a continuation of that - we'll see. They have a talented team and have maintained the level of talent well since the end of Pat's reign and with the 2017 class signings that appears to be continuing. They have also had a fairly constant string of injuries which happens to most teams, but seems to have perhaps nicked the top of their talent more than 'average' in the women's game. All that said ...
I have not seen anything from Holly and her coaching staff that suggests to me that they are very good - it seems that for all her years in the profession and working with Pat, the extent of her take-away is 'Intensity and commitment' win games - listening to her, she just doesn't seem to have very good analytic skills. That may just be that she is not a good public speaker, but watching her teams play, and her own performance on the sideline with substitutions and game management doesn't contradict that impression. All of last year her team appeared to have no clue how to run offense against a zone, and it was never dealt with even after it led to some losses. That to me is an indictment not just of her, but of the whole coaching staff.
TN will win games and advance in the NCAA based on talent alone, but unless something freakish happens in the bracket, I will be surprised if their talent alone is sufficient to get them to a FF. By the second weekend of the NCAA the talent of the coaches and the teams remaining poses a real challenge for a team coached by Holly. And TN for the foreseeable future will still have enough cachet to attract top end talent which will likely keep Holly employed.
