So for a top F or D prospect who is likewise 2-3 years from making any impact in the NHL. It's alright, but it comes back around to: who is that prospect?
I don't personally think it needs to be just a prospect, it could also be an established player. In fact, an established player who fits a need might be better for the short-term window mindset than another prospect at a different position. The problem then becomes the Cap. The Preds are Capped out atm. And all the teams in the NHL have already filled their major and minor league goalie slots and won't be clamoring to get Askarov just now. So... maybe we're talking more about a Trade Deadline type of move? Not necessarily for a pure rental player, but at least a player the Preds pick up for immediate help, once some Cap leeway/pro-rating is in place?
Well, to me, it all still comes down to just evaluating the specifics. Sure, the Preds could trade Askarov. But "now"/"TDL"/"later" still comes down to all the usual questions about evaluating the net benefit to the Preds and the Cap feasibility, etc. And how Askarov performs.
