He also got into a very heated argument with a reporter IIRC. Ratliff definitely has some issue with anger management. You could also see evidence of the "Good Jay" and "Bad Jay" at the police station this past arrest.
What sane person threatens to fight his 70-year old boss?
A) He isn't mentally stable IMO.
B) He is injury prone and his physical football health is declining.
C) He is paid way too much for his likely production.
Conclusion: Dump this high-maintenance, injury-prone, highly-paid player. Better for the team, and better for Ratliff in the long run. You CANNOT reward bad behavior like that. Let Ratliff realize his shortcomings and maybe get help. A fresh start in a new location would do wonders for all.
