that argument lost credibility when the vets we've had the past few years where losing games in the 4th quarter (or coming out in any quarter with horrible effort).
good players who are hungry for winning will win games. less-talented players, players that make the same mistakes over and over again (regardless of experience) or players without that desire to compete hard every night to win will continue to lose.
According to that argument though, Michael Jordan, Dwayne Wade & Kevin Durant all had a strong desire to lose rather than win early on in their careers.
I think our guys are playing hard and I also think that (Olynyk, Sully, Bradley, Green and Vitor) are all tough, hard working and intelligent guys who want to win.
If we bring back a healthy Rondo, get a high draft pick and sign a max player at a position of need over the next two off seasons, I have little doubt the above mentioned young players will be a very big part of a team contending for the ECF.
Veterans who dial it in are a completely different scenario.
As far as making the same mistakes over an over again - how many times / years was it we had to watch that future hall of fame guy Paul Pierce make the same incredibly bone headed plays?I think he dribbled into about 700 double and triple teams over his first 8 seasons.
