We have been searching those RHDs since start of the rebuild, if it would be that easy I think there wouldn't have been problems at all, but always has been until Holl emerged. You listed five players and we have fantasized about Josh Manson for years. In real life David Savard was expensive asset until this years deadline. Toews emerged trough AHL as 25yo and was bit of a wild card. In Oleksiak and Edmunson their teams stumbled on those players right time. Like we did with Holl. We have tried UFA routes, we have signed lefties like Hainsey, we have went to europe (Oz and Lehtonen as lefty).
Thing is that if we lose Holl in expansion draft we have one or two shots for suitable players and that's it, then you have to overpay. I think Dubas knows how much top4 RHD costs in the market right now. His discussing with other GMs daily. Bogosian is option
@Mess likes to point out, but if he wants to move to States it's no go since his UFA.
I wouldn't be surprised if Holl could elevate his game a bit more here. His been late bloomer and earned his place in every league trough hard work and ability to adapt and learn. I'd count that he has smarts and good head on shoulders, so I would be hesitant to expose him. I think we could get more for Holl than McCann, Kerfoot or Dermott on trade market.
