You have a drastically different view of the guys LeBron played with than I do.
That Cavs roster wasn't particularly talented, but this was something I was thinking about the other day:
It was kind of a perfect cast for Lebron, and they might not have needed that much more.
Defensive center to protect the rim, stretch 4 for spacing, and a great shooter at the 1 who doesn't need/want to bring the ball up the floor.
Perhaps what they needed was some more consistency out of Mo Williams and another scorer at the off-guard.
EDIT: And yes, I bashed that team about as hard as anyone else.
DOUBLE EDIT: I have an uncomfortable amount of love for Chris Paul, but he's not the best player in the NBA
I've got no qualms with that analysis, but I'd like to phrase it a little differently.
I think that squad was constructed perfectly to complement their respective talents with LeBrons, but it had a low ceiling. Its the difference between the Spurs' recent team built around Dirk, and LeBron's Cavs team.
One team had HOF talent, and a smartly and uniquely fit supporting cast.
LeBron is maximizing a Honda civic in Cleveland. But Dirk was messing around with a Lexus.

There's some truth there, and I'll make one last point b/c I don't want to derail the conversation too far:
But I don't think the difference from Lebron's Cavs and Dirk's Mavs were as significant as you suggest. In fact, they're surprisingly similar - though the Cavs counterparts are kind of 80% of their Mavs equivalent (Varejao isn't Chandler but he's kind of close, Mo Williams isn't the jet but he's kind of close).
Again, I don't want to derail things too far with a random thought I had which was really wondering if you could argue solely from a basketball stand point that staying on the Cavs might've been a better move for Lebron.
The Mavs had a much better supporting cast. Just look at the rest of the starting five and the bench of those teams
Kidd v. Hughes - Kidd a much better floor general, shooter, and rebounder, but Hughes was a more dynamic offensive player - edge Kidd
Stevenson v. Pavlovic - defense v. offense, but Stevenson was a better all around player - edge Stevenson
Marion v. Gooden - even at Marion's age, he was still better than Gooden in virtually every aspect - big edge Marion
Chandler v. Illgauskas - Z was a much better offensive player and still a pretty solid rebounder, but he was no where near the defender - slight edge Z
Terry v. Gibson - Boobie would be lucky to be called a poor man's Jason Terry - huge edge Terry
Barea v. Snow - Snow was old and slow, but still a decent floor general, but he wasn't as good as Barea - edge Barea
Haywood v. Varejao - Very similar players, but at this stage Haywood was the better player - slight edge Haywood
Stojakovic v. Marshall - very similar players at that stage of their careers, but Peja was more effective and put in more minutes - edge Peja
The Mavs were better at virtually every position and the one they weren't was arguable. If Lebron had Dirk's supporting cast there is a very good chance they would have beaten the Spurs and won the title in 06-07 (afterall the Cavs lost the two games in Cleveland by a combined 4 points and Hughes didn't even play in those two games - thus a little better supporting cast could have meant wins in those games for sure).
