to put this in context ... i'm not / wasn't a fan of jones, seemed like to me he had a bad attitude, and refused to play defense (which is different than a guy who isn't great defensively due to athletic reasons but tries hard)
but on the merits of him (jones) making last year's team better ... i don't believe it's clear one way or the other ... how does he handle getting fewer minutes? does he pout? does he play hard when he does get minutes? if he doesn't, do the coaches give him more or fewer minutes? could be wrong about this, but wasn't he a cyprian guy, and how would he handle not having cyprian around?
no question if he'd have had a good attitude and accepted fewer minutes and fewer shots he could have helped, i'm just not sure he would have, i tend to think he wouldn't have handled it well and it would have been a drain on the team
from a talent standpoint ... the team would have had more talent and depth with him, period. i'm not convinced the team would have been better because i think his seemingly poor attitude would have been a negative, but he's a talented offensive player who had (still doesn't, see nba summer league) no interest in playing defense
on the transfers hurting question i sent to you ... my initial question was focused on this years transfers ... i think on balance what was gained this year v. what was lost is a + ... we'll have to see
the other transfers / lost players during kennedy's tenure ... all the way back to middleton were definitely drains on talent, even hibbert and alexander (neither of who were good players) because what they picked up at best was a push, at worst was a down grade, no doubt about it those were net loses, especially middleton ... i think the jamals weren't good team guys and while you clearly lose talent without replacing it, those weren't going to be good teams anyway and whatever team / program culture is worth was probably helped to some degree in the long run by the jamals leaving sooner rather than later
as far as excuses for coaches ... my opinion is there are reasons and circumstances which lead to better or worse years for coaches, but there are no excuses for coaches, they get better or worse each year, they're rightly evaluated on wins and losses over some period of time and if ad's feel like what they're seeing isn't improving / building a better program at an acceptable rate then they get fired and someone else gets a try
