If Askarov is unwilling to report to Nashville's AHL team, why would he report to our AHL team? He would be agreeing to another year of AHL play, a year after that splitting time with Markstrom, and likely not starting until 2027.
You could maybe talk to his agent and work out a wink-wink-nudge-nudge 'keep your guy quiet in the AHL this year and will give him a fat RFA deal next summer' kind of arrangement. But quite frankly it seems like he's interested more in playing time than in money.
Otherwise we would have to trade Allen to open up a spot, which is kind of a scummy move considering he waived his NTC to be here (and would need to waive it again). I get that the league is a business and all is fair, etc, but I think Fitzgerald himself would be reluctant to that. Especially considering that he'd be going from a proven vet to a 22 year old kid, I just can't imagine him being okay with that risk when our window is right now.
