Wrong, its a perfect exercise to exhibit his greatness, for people that have no eyeballs, and need more evidence
If the rosters remained intact, other than Lebron leaving, I'd agree.
It would be similar to when MJ went to play baseball for 2 years, but the Bulls roster stayed mostly intact and they went to the ECF without him.
The closest may have been when he left the Heat, but even then, they added players and lost Bosh after 44 games and D-Wade missed 20 games.
I think that if Bosh and Wade stay healthy, we may have seen a Cavs/Heat ECF, which would have been pretty cool.
Of course, Wade's health was part of why Lebron left. Sooo...
