Jimmy Butler’s numbers have improved. So too have his leadership skills, with a little help from a new Bull. “Last year, he had his times where he was a little frustrated and he didn’t know how to let out,” Taj Gibson said. “This year, having (Dwyane) Wade helps him a lot. He can learn from him. He can understand.” That’s a trick we can get behind, unlike this one from David Blaine (Butler agrees). Now, let’s see what Wade can do with Jerian Grant, who went from inactive for three games to starting against Portland and scoring 18 points. Grant will start again tonight vs. Jazz in the late show (9:30 p.m., TNT).
