Jones is an arrogant man, and he knows that everyone expects him to fire Phillips tomorrow. Hell, the only reason why Wade has the job still is because Jerry has this sick, twisted humor where he gets a ride of doing the opposite of what everyone wants him to do.
He's not going to fire wade because he doesn't want to give anbody pleasure or the satisfaction of his failures. He's going to make that miserable oaf ride the rest of his 1-15 season. Eat the contract for the rest of the year, enjoy the lockout on the beach to clear the mind, and start the team from scratch.
