Roman Modrowski of ESPNChicago.com reports the Bulls are checking into the health of Tracy McGrady's knees and have spoken to his agent, Arn Tellem. While TNT analyst David Aldridge adds that McGrady will work out for Chicago on Monday. Nick Friedell of ESPNChicago.com doesn't think the Bulls will sign McGrady. Friedell writes: "Here's why I still don't think the Bulls will pull the trigger: At his peak, McGrady was never known as a great defender. After several knee surgeries, it seems as if he's lost at least one step, probably two. Does that sound like the type of player that would fit right into new Bulls head coach Tom Thibodeau's system? I don't think so." McGrady completed his two-day visit with the Clippers on Wednesday and tweeted, "clippers, bulls, lakers, heat ... but that could change by the morning ... lol ... this is the NBA" and later, "yes, there is a chance ... i love the bulls roster ... minutes take care of themself ... i want to win."
