Weaver was drafted in 2008 by the Bobcats and then traded that summer to the Thunder for a second-round pick. He played quite a bit in his rookie season, putting up decent numbers. He didn't play much last season and was cut last year while trying to make the Bulls.
Ridiculous Upside had this to say about him in a DLeague game last season,

Oh! I haven't even talked about the guy who might've been the best player out there, Kyle Weaver (helpfully listed as Eric Smith in your box score). Simply put, he's a fantastic defender covering multiple positions, and ran the point for some stretches while Shakur sat, doing a pretty decent job of it. He also grabbed 10 rebounds and had two blocks. To be sure, Weaver is no great offensive player; he missed several layups, either bricking them or seeing them roll out. I'm not sure if it's an accuracy issue, or one having to do with misjudging how hard or soft to shoot; given some of his other shots, my guess is accuracy. Still, he got into the paint whenever he wanted.
The Jazz did bring him in for a workout before the 2008 draft,
He appears to be a combo guard who's a shoot-first guy but will give the Jazz a bit of depth to close out the season should Harris and Price not be able to return soon.
