I think the expectations were way too high on this one. Lake Show has rarely added a major star to the roster and shown a substantial improvement.
Wilt - team improved from 52 to 55 wins
Kareem - team improved from 30 to 40 wins, no playoffs
Shaq - team improved from 52 to 55 wins
Mailman - team improved from 50 to 56 wins
None of these teams won a title, although Malone's addition got them to the finals.
Lebron - team figures to improve by 7-10 wins
About what one should expect considering past history.
