It’s been nearly three months since Derek Fisher left Dallas. The Dallas Mavericks are not particularly big fans of Derek Fisher these days. Because Jeff Fisher has always been a guy that players want to play for. Fisher played nine games with Dallas before asking to be released because he said he was having a difficult time being away from his family in Los Angeles. Dierdorf, who covered Fisher’s Tennessee teams for a long time as a CBS television analyst, said Fisher’s recruiting acumen shouldn’t be overlooked in landing a player such as Long. In December, owner Mark Cuban agreed to release Fisher following a short stint with the club so that he could rehabilitate his injured knee and focus on a major NBPA power struggle it was in many ways a personal favor. “I was really disappointed when he left without signing,” said Hall of Fame tackle Dan Dierdorf, who like Long is a University of Michigan man.
