You don't want those kind of guys under contract, you want young guys in those roles. Plus there's a limit for how many guys like that you can have.
Ideally you could somehow slip Ponomarev through waivers and run with something like:
Ilyin-Broz-Bemstrom
Poulin-Ponomarev-Hayes
I'd bring back at least one vet AHL scorer lik Bemstrom or Katchouk and then I guess it depends on if Ilyin's going to be in WBS or Cherepovets plus if they leave an NHL spot open for Poulin and Ponomarev to compete for. Two AHL vets with NHL experience would make sense, with one of them being a centre.
