Problems off the top of my head:
-AB quit on his team over a Team MVP,  
-attends practices/meetings if he’s in the mood                                                 
-trading team must give up pick + pay him          
 -10th year at a position that doesn’t matter  
-Legal issues from domestic violence to throwing furniture off a balcony. Add the driving 100+ mph, threatening to break reporter’s jaw, etc.                                
-Seems mentally unwell (see above, his Twitter, Mr Big Chest, mentored by TO/Ocho
 -Throws tantrums when seeing less than 15 targets/game
  -would rather lose and put up 10-150-1 than win and put up 5-50-0.                  
-replicating his stats is highly unlikely away from his youth, his first ballot HOF QB and always loaded offense (how would he do in JAX?) 
-because replicating his stats is highly unlikely, he could go insane immediately
Pros:
-Has been excellent on the field.          
 -Could have 3-4 prime years left.                       
-Would put butts in seats.                    
 -Could buy time for a GM on his last chance (Mike MacCagnan?)
