Believe me, LeBron leading the league in minutes will have an effect come postseason (he's averaging TWO minutes more than last year). And even if we were to ignore those long term postseason effects of his min averages; it doesn't bode well when this squad can't beat lottery teams on a regular basis with him playing nearly 40 mins a night. He was suppose to take a back seat this season and then ramp up his minutes near the back quarter - that hasn't happened - in fact it's been quite the opposite.
There's a # of teams in the East that can push them (even if not one team, but a three-team collective effort), certainly more than the Finals cakewalk they've essentially had for the last two years. If the Cavs keep continuing along this path with no squad alterations or notable improvements, they'll be gassed out before they even get to the Finals.
