This team could be the greatest in NBA history based on sheer talent. I don't think any but 1 or 2 have even come close to the trio that is KG, Allen, and Pierce. Considering they're only a little past their primes, they could be the greatest collective talent in NBA history. And despite popular opinion, the surrounding players aren't so bad. Rondo and Perkins are solid for what their roles demand of them. Big Baby, Powe, and House are actually pretty good role players when they decide to play within their strengths and contribute. Very few title bound teams have had a weapon like Tony Allen that when energized could clear his own HOF worthy teammates out and flat out score. Technically, this COULD be the greatest team in NBA history, if they wanted to. Why aren't they then?
Simple: Attitude.
This team has the "wrong" kind of attitude. Put them in the "hubris" category that the Patriots of '07 were guilty as charged of when their initial self assurance and modesty turned into overconfidence. There's a reason the "other" bench laughs at us all the way to the tunnel after a not-so-hard fought loss. They shove in the fact that we're good, we know we're good, but lack the sheer firepower to carry it out on too many nights. Even looking at the wins of the last 1.5 years, there are too examples to see from that embody the lack of spirit and selfishness where we gave up leads, made it possible for them to generate huge runs to come close in an unfathomable way.
Real winners don't let this happen to them. People like to bring up the fact that for two years running, we've had the best W/L, but that stat alone is meaningless. W/L is more of a representation of preparation. And we're inherently more prepared than many other teams even when the opposition puts in "effort" while we don't because we're at a great advantage with our players. Like a team against MIL might fight us hard, but they lose for a reason, and it's not "heart."
I don't know, losing 4 out of 6 games (two wins coming against the high and mighty Kings and Wizards, lol) shows we're mentally too weak to develop resiliency. And it's not a talent issue. It may not even be a coaching issue. I just think our guys are a bunch of selfish egotistical losers who try to sell the notion that they're hard working, selfless guys all on the same page, but it's just not true. That's the root problem. And I think 98% of you will deny it, but it's true. The bad mouthing, "yapping" is just a surface example of the me-first attitude (personal agendas to show the world what they're made of... aka KG). As is the Ray Allen and Rondo confrontation during the LA game which resulted in Pierce shoving Ray aside to cut it out... but they clue you in on the lack of harmony between everybody on this team.
