Is he better than Mantipalo or Guenette? If so, what makes you believe that to be the case?
I honestly had never heard of him before someone brought him up as a potential waiver claim, had you?
First, nope, never had heard of him. Did some investigating once I did though, and believe he would have been a worthwhile target (for many of the same reasons others have posted).
Regarding Matinpalo and Guenette...
At 26 and a year in NA, I had hoped that Matinpalo would be pushing for a spot in Ottawa but maybe he's still getting used to the NA ice? Apparently he has a hard shot?
Guenette is a bottom pairing guy at best, from all accounts. Really no room for him in Ottawa at this point.
My take on Regula is that he was close to making the jump to the NHL full time but suffered a knee injury. The Sens had room for his contract, pick him up, rehab him with the big club, worst case he gets waived and lost, best case he provides depth at RD.
Seems like an opportunity missed by a team with limited draft capital and still mired in a rebuild.
