Pope killed Leroy cause he got his daughter killed by tig in the hit and run. He shouldnt have though. Tyler is like the QB from blue mountain state. He had no plans to ever be in charge then got the job due to to the star going out in a freak accident. Dude went from weed carrier for leroys weed carrier to head of the whole gang. He's in way over his head and jax the only one walking him through it.....until its time to blame the blacks again.
You can basically say Jax runs the 9r's like Russia runs the Ukraine.
