I think you just plan to let Ras run as the RHD next to Gio for the 1st half of season and give a chance to actually acclimate to the change. If he's struggling by late January, you take a look at the trade deadline market.
That should be our general outlook on a lot of these positional battles tbh. We have a bunch of young but pro aged guys who can potentially fill these gaps. Seney, Steeves, Douglas, Anderson, Abruzz, McMann, HoSang, Niemela, Kokkonen, etc, etc. We're developing a bad habit of giving our AHL guys a cup of coffee, deciding that they're no good and punting on them, only for them to look like functioning NHL options in their next city who gives them an extended chance, then picking off the reject pile of other organizations to try to fill our gaps on the NHL club with varying levels of success.
If you can pick up a "Nick Paul" every year at the deadline for a 4th, why go chasing them in the summer if you have in house options to assess for a few months?
