It’s looking more and more like goaltender Pekka Rinne will play in all of Nashville’s 10 remaining games. On Friday, coach Barry Trotz said he originally had a plan to work in backup Chris Mason this weekend in a back-to-back with Chicago. But with the Predators’ playoff position looking ever-more tenuous, Nashville feels like it must use Rinne as much as possible. “Right now we don’t have any wiggle room, so you have to go with your best. We had a plan way back when we started that (Saturday’s) game would be Mason, but things change,” Trotz said. “Right now we have to go with our best, and Peks is our best.” The schedule actually looks favorable to use Rinne moving forward with only two more back-to-backs — one of which in mid-April has both games at Bridgestone Arena. The first game of the Predators’ upcoming back-to-back Saturday against Chicago is at 2 p.m., which should give Rinne more rest for Sunday’s 6 p.m. contest at the United Center.
