Cavs
Way back, in November of 2003 I wrote that LeBron James was a Godscend for Cleveland, but also wrote that I was expecting something to go wrong at any moment. Why? Because it's Cleveland. Something always goes wrong.
I expected James to blow out his knee, but instead, for a year, he carried the Cavs (and Cleveland sports for that matter) on his back.
Then, Gordon Gund sold the team to Daniel Gilbert, who apparently decided that despite the fact that the Cavaliers were heading for the playoffs for the first time in over half a decade, that wasn't good enough.
So within two weeks of taking over, he fired everyone in sight and turned the organization from a rising contender to what it was before the LeBron arrived-- a laughingstock.
I make it a point never to agree with Stephen A. Smith, but the man actually had an interesting and truthful piece of advice to Gilbert:
"Back off and write the checks."
Right on.
