Below is straight from:
“The latest victim of WWE’s dreaded “future endeavors” announcement was The Brian Kendrick, and a PWInsider report sheds the first bit of light on the matter.
According to the report, Kendrick’s release can largely be attributed to his backstage attitude and motivation as a performer. The internal feeling was that while Kendrick did what he was told, he carried a negative attitude and gave the impression that he did not deeply care about being there. WWE thus saw little potential for Kendrick to breakout as a valuable member of the roster and opted to sever its ties with the wrestler.
It remains to be seen if Kendrick’s release is a compounded consequence of his behavior or if a specific incident brought WWE officials’ concerns to a boil.
Sources are also quick to mention reports that Kendrick was one of WWE’s most frequently-fined Superstars for marijuana use, although it is unclear if that played any role in his release–under the Wellness Policy, there is no punishment, beyond the fine, for using the drug.”
So he didn’t get canned because of Jerry Lawler. I doubt he smoked marijuana as much as is being infered. An athlete (and wrestlers are athletes) needs lung power and mj kills it. He did his time in WWE, now he will be a god on the indy circuit.
