I honestly think the only reason Askarov isn't on the roster over Vitekwood is for the same reason Schmid kept getting sent down as soon as Blackwood would come back from injury, despite being the far superior goalie that season. They aren't gonna waive either of those guys, as both are on expiring deals and would probably be claimed. And they won't do the three goalie thing, just like we wouldn't. Most teams won't, but a few of them have been doing it for a while. Detroit being one of those teams.
But I didn't follow the Sharks preseason enough to know if Askarov had a poor preseason or camp. He looked great in the couple of games he played while Vitek was injured recently. Best numbers on the team, but he only played 2 games and was sent right back when Vitek came back after a week or two injured.
He's the only guy I may one day regret not picking up, especially since Markstrom/Allen are old and Daws is still a gigantic sized question mark. And not to mention we could have even picked him over Holtz back in the 2020 also!
But yeah, Saros, Swayman and Hellebuyck were never made available. I suggested Ullmark a year ago, but was more interested in maybe renting him for a year, and was fearing what we might have had to extend him for.
