The Bulls were on the embarrassing end of a video making the rounds on the Internet. During Saturday's blowout loss to Toronto, Raptors guard Jarrett Jack caught a pass and with two Bulls defenders looking on, Jack bent down and tied his shoe while still holding the ball. The incident had no effect on the result, but it did make the Bulls seem a little lax defensively. "That was embarrassing," guard Derrick Rose said. "I probably would have fouled him or something." Coach Vinny Del Negro didn't excuse the shoe-gazing. But he offered the explanation that forward Luol Deng and guard Jannero Pargo were trying to execute a defensive switch while the clock counted down at the end of the third quarter and didn't notice Jack's shoelaces. "Luol turned his head as Jack was doing that," Del Negro said. "That's not acceptable, but it was also a unique situation."
