The Bulls aren't completely sold on signing Tracy McGrady, according to sources with knowledge of the team's thinking.

Following his workout with Chicago on Monday, McGrady spoke as though he was already a member of the team.

"I think we can be really good," McGrady said, "I really do."

One source said McGrady looked good physically during Monday's workout, but the veteran still hasn't convinced the Bulls that he'll embrace a reserve role.

Another source put the chances of McGrady signing with the Bulls as "unlikely."
