The Cavs will retire Lebron James' jersey eventually. As much as I disliked how Lebron did "The Decision", time heals all wounds.
Even now, even though I still dislike "The Decision", he has shown a measure of maturity the way he handled himself THIS time in CLE vice the last time. That is to be considered, IMO.
Eventually, I cannot see any reason why CLE doesn't retire his jersey. What he did there is admirable, even if he couldn't bring them a banner.
