Antawn Jamison got his first start for the Cleveland Cavaliers last night and helped the Cavs end a season-high three-game losing streak.  Jamison played 37 minutes, going 7-14 from the field and finishing with 18 points, 6 rebounds, 2 assists, and 2 steals in a 105-99 win over the New Orleans Hornets.  Jamison has now put together two good games after a horrendous debut with the Cavs.  In his first outing after being acquired in a trade from the Washington Wizards, he went 0-12 and finished with just 2 points.  He bounced back well in the next game and had 19 points, 8 rebounds, 1 steal, and 1 block in 31 minutes off the bench.  It looks like Jamison quickly forgot about that terrible debut and is already settling in nicely with the Cavs.  He has looked like the Antawn Jamison everyone has grown accustomed to seeing in his 11 years in the NBA, where he has career averages of 19.9 points, 8.1 rebounds, 1.7 assists, 1.0 steals, and 46% FG shooting.  .
