I think his 'plan' is that of all new bosses: to make his mark by filling all the positions he can with 'his' guys, and that of course means getting rid of 'the other guy's guys.' Thus Betts, Bogey, Beni ... guys like that just don't count. And if he can save the owner millions of dollars in the process, great!
All the lying, hypocrisy, contempt for players and fans ... that's just extra.
