5 PTO guys I'd look into:
Mason Shaw: A tenacious forward who plays big for his size. He's gritty on the forecheck, and has shown to be an effective penalty killer. I believe he also has some untapped offensive potential, as he has good playmaking skills. If his knee is better, he'd be absolutely worth a gamble.
Noah Gregor: A winger with blazing speed. He's defensively responsible and is physical on the forecheck. I could see him developing into a good penalty killer. Worth a gamble on a PTO.
Tyler Motte: High Energy, high tempo player who is a great penalty killer. We need another killer, and I think he'd be a nice add.
Paul Stastny - With our 4c spot being completely open bringing in an experienced vet isn't a bad idea. Great on the faceoff dot, and can chisel in offence when needed.
Ryan Spooner: Here's my off the board pick. Guy hasn't been in the nhl for a few years but has been very successful at the KHL level since. Could add a scoring touch to the bottom 6.
I'd bring in 2. PTOs add more competition to training camp and sometimes they work out. No point in not trying out a few guys hoping something sticks.
The whole idea is we have 1 forward spot available (likely the only spot available). Let's make it difficult.
