Don't downplay Lombardi's chances here. He is a skilled player. When he came to the Preds there was a real sense of excitement over his offensive abilities. Injuries, of course, have derailed his whole career.
If he is healthy (a big if) and can still perform (also an if), he may be the perfect short term answer here. It would be a big responsibility to plug a first year pro like Hayes into what is essentially our first line.
When we signed Lombardi, I looked at him as our "wild card" player, possibly able to fit in anywhere if needed. His experience in the NHL may give him a leg up here. If we were talking a 2nd or 3rd line center vacancy, I would absolutely say we should go with Hayes, Miller, or Linberg. But 1st line center is a big deal. If healthy, Lombardi could possibly hold down the fort until November. Absolutely give Hayes a shot here in preseason, but if this is to much, consider Lombardi.
