100% sure now.
We would know if he was leaving Miami right now hell we would have known a week ago. Tomorrow they announce his extension along with Wade and Bosh's deals (which were already worked out I am sure).
Here is what I think. Lebron would not string Pat Riley along like this. If Lebron was leaving he would have had the respect to tell Riley weeks ago so he could have made other moves for bigger ticket free agents and be able to field a team. Sorry I just can't imagine James ####s on Riley, Arison, Spo, Bosh, and Wade and the city of Miami like that after the last 4 years. Cleveland may think he #### on them…but he gave them 7 years and that owner is a putz.
