"His development has been great this year," Housley said. "Not only is he doing really well on the power play, he's playing a 200-foot game. He's really responsible and plays the penalty kill as well. His wall play is good, and obviously his shot is incredible.
"Just looking at it this morning, it was great to see him have a shooter mentality. It will be interesting to see what he brings to our group."
Olofsson said he's taken on added responsibilities as the season has progressed in Rochester, including time on the penalty kill.
"My defensive play has been better," he said. "I feel that gives me confidence on offense too. I feel really confident with the puck. That's helped me a lot."
Olofsson will be the third player to join the lineup from Rochester in the last three games. Lawrence Pilut stepped in on defense in New Jersey on Monday and William Borgen made his NHL debut the following night in Ottawa.
Borgen tallied three hits in 14:54 and stood out for his simple, defense-first game.
"I thought Will played great, stepping into a situation where he had to drive up from Rochester," Housley said. "He was excited, the adrenaline was running, but he played a really solid game. Very simple game, joined the rush when he could, was good defensively, hard to play against."
The Sabres assigned Tage Thompson to Rochester this morning, where he'll join the Amerks for their playoff run. Thompson, 21, tallied 12 points (6+5) in 65 games with the Sabres this season.
"I think it's all part of his development and his plan," Housley said. "He got some meaningful games up here, did a really good job, but it gives him a chance to get acquainted with his new teammates, get some meaningful minutes and get ready for the playoffs."
