The form is the same, but the arc is a bit different. So is the look and feel with which Omri Casspi is playing this season.

Casspi arrived at training camp insisting he was done talking about last season. It was a miserable year: He knew it, fans knew it and coach Byron Scott knew it. He spent the summer trying to put a little more arc — and by extension some confidence — in his jump shot. He kept everything else the same.

Casspi entered Wednesday making 50 percent of his 3-pointers, tying him for fifth in the league. It’s a drastic improvement over last season, when Casspi shot a career-worst 32 percent on 3-pointers.

“It’s a [result] of the hard work I put in,” he said. “I feel I can shoot 40-plus percent [on 3-pointers]. That’s what I need to go for. I’m confident.”

Casspi concedes he never had much confidence in his shot last season. Now he looks more comfortable on offense, has shown fast hands to poke passes away on defense and is finally resembling the player the Cavs thought they were acquiring two summers ago.

Casspi has never shot 40 percent in his career from 3-point range, but believes this might be the season it finally happens. The Cavs are shooting 36 percent on 3-pointers as a team to rank in the middle of the league. They were ranked sixth entering Monday’s game at the Memphis Grizzlies, but have shot just 6-of-31 (19 percent) on 3-pointers the past two games.

The team’s best 3-point shooter, Daniel Gibson, remains day to day with a bruised right elbow. Gibson had an MRI on the elbow Wednesday, which revealed no new damage. He has missed three of the past six games with the injury.

Dion Waiters’ MRI on his left hand came back clean and he has been cleared to continue playing. He injured his ring finger in Tuesday’s loss to the Phoenix Suns when he banged it on the rim.
