I'm not saying y'all don't respect him but IMO he hasn't done much for his jersey to be retired.
It depends on the franchise and the quality of players that come through the organization. Obviously he played for a team like the Celtics or Lakers he wouldn't have his number retired, but Cleveland doesn't see to many players come through their organization that are good players. Much less stay with the same team for 12 straight years which is almost unheard of now-a-days.
Personally, I think he deserves it to be retired for the Cavaliers franchise. He was a great player minus the foot injuries, showed dedication and respect.
Ilgauskas was a Cav for many years and was extremely loyal. Doctors told him in 2000 to retire, but he kept playing. He missed all of 1996-97 and played in just 29 games from 1999-2001. Then add his wife giving birth to stillborn twins and he went through a lot. It's not like he was a scrub. He was pushing a double-double with almost 2 BPG at his peak. He deserves to have his number retired. Couldn't have happened to be a better guy.
