He thinks he's better than he really is.
Btw why the hell is he captain over Saul?
I think the bigger problem is he thinks he is the best in the world ...
If someone could have just found a way to taught him not to be that selfish over the last 2-3 seasons ...
And still, I think it won't be such a bad decision to take him back for this amount, since we could ship him for around 10 mln next season if he keeps doing his "things" ...
I really thought he could develop and erase most of the bullshit from his "arsenal" ... so maybe one more final shot in the dark with him ...
