i do believe the cavs will still be THE team to beat in the east this year. but as was hinted at above with his back problem, lebron's window as a transcendent and HOF player maybe be close to starting to think about closing.

aside from the shot for his back and missing the pre-season, lebron is 31 and is coming off his worst statistical season in 7-8 years (including a .487 ts% in last year's playoffs).
he has now played over 43,000 total career minutes (which is more than Bird or Magic played their whole careers), and has talked to the press about how his body doesn't feel the way it used to, and how he could have used a lot more rest this summer, and adopted a "special diet."
this is NOT to say he is breaking down and is a has-been. but i think lebron's humanity may be tapping him on his shoulder. what this means is that the cavs absolutely are all in, win right now, no delays, screw tomorrow.
