Again, i think it's pretty much a guarantee that he had other 1x $875k type offers on the table. He simply didn't seem interested in signing on anywhere to be a low-usage 2-3G somewhere. Because the Preds experience had worked out so poorly for him. At some point, it's very evident that while much worse goalies were signing on still for that kind of money or more on 1-year sort of deals to play competition for a backup spot...Lankinen had decided to sit back and wait for a better opportunity to come along. As that was the only way to realistically earn his way back to a $2M+ multi-year deal sort of consideration. Taking low-usage backup type money for a year, to earn his way to a real multi-year deal and opportunity to play at least a tandem role later.
At the time, i didn't know if it was the best strategy either. Risky to some extent, but it was pretty clearly what he decided to do. And at that point...it was clearly a decent gamble to wait for an opportunity to play, rather than sign on wherever was offering, only to be potentially buried and barely see the net at all. Everyone that pays attention knows that every year, opportunities arise out of desperation throughout the season. He got lucky in that the Vancouver thing came to a head much earlier than other goaltending situations...but there were always going to be opportunities that opened up. Every year, many teams end up with goaltender injuries or guys just falling off a cliff and delving at least 3 rungs deep on their goaltending depth chart. That = opportunity. And Lankinen clearly bet on the idea that waiting and playing even half a season in a good opportunity, was a better way to showcase what he can do, than just re-signing for cheap with Nashville or whoever, in a situation that had just tanked his "value". Like...why would he agree to the same sort of situation that just nuked his career prospects, all over again?
Like...Preds goalies who aren't Saros have started a total of ~13 games this year. Lankinen alone has already had the opportunity to start 32. That's where realizing Demko's situation was pretty significant, Lankinen jumped at the first real "opportunity to play" that came along. Where it was clear he'd get a good run of games, even with Silovs around and not knowing how much he'd struggle this year. It was still promising a lot more than a dozen or so starts through most of the season.
