The other big difference with this team is that teams don't fear the Celtics anymore especially in Boston.
The Celtics of the last couple years had such a killer instinct. The first halves they have played in the last few games would have resulted in 15 point leads easily. This years team gets ahead then gets lazy, makes a turnover, misses free throws, get beat for rebounds,gives up a wide open 3 pointer === little plays here and there that add up. It doesn't take much to give an opposing team hope and the Celtics have mastered the art of letting teams back into games.
And in this day and age, teams know exactly what is happening. I can almost hear Detroit't coach tonight at halftime telling his terrible team to "just hang in there, these guys blow big leads almost every night" Even a team that is decimated by injuries and has lost 14 of 17 games can come back against this Celtic team.
KG coming back will undoubtedly give the Celtics an emotional lift. It should be enough to get them playing well for a few games. But it will not be enough to turn this season around --- make no mistake there are great issues with this team that are painfully obvious to anyone watching the teams recent collapses especially against some of the NBA's absolute worst teams...
