If this is it, if this is the end of Daniel Gibson’s time with the Cavaliers, he readily admits he is terribly disappointed. Gibson will be a free agent at the end of the year, and there remains at least a decent chance he will not return. He has spent his entire seven-year career with the organization, but has only appeared in 45 games this season because of injuries to his elbow, toe and ankle, a concussion and the fact he fell out of coach Byron Scott’s rotation a few weeks ago. He is again sidelined with the same elbow problems that bothered him near the start of the season, and it’s unclear whether or not he’ll play in any of the Cavs’ final three games. Gibson said he has given a lot of thought to the fact Monday’s game against the Miami Heat could be his final home game at Quicken Loans Arena. “It’s really stressing me out. It’s kind of upsetting,” Gibson said. “I hate the way my last season went. Just with all the injuries and everything I’ve dealt with. Me and this city have a really close bond and connection. I feel like I owe them more than I gave them this season.” Gibson is averaging 5.5 points, his lowest scoring average since his rookie year, and he’s shooting a career-worst .346 on 3-pointers. He is making $4.8 million this season and will be a free agent this summer. If Gibson has any chance at returning, he’ll be facing a significant pay cut. “If there is any role I could be part of the Cavaliers moving forward, I would accept that just to finish on a better note,” he said. Gibson’s scoring has decreased each of the past three years, and his shooting percentage has declined each of the past four years. He moved into third place this season on the Cavs’ all-time list of 3-point shooters and now has 578 in his career. But he has also battled injuries nearly every season.
