The Utah Jazz and forward Carlos Boozer are being cautious with their optimism, but it looks as if Boozer may come back sooner than expected. Boozer returned to practice Christmas Day and said the left hamstring he strained Oct. 6 is almost completely healed. Is it a coincidence he’s feeling better after Utah made its one appearance in Cleveland on Dec. 20? Boozer is best remembered in Cleveland for allegedly reneging on a promise to re-sign with the Cavaliers after the 2003-04 season.
