We wouldn't have made the playoffs if the pandy didn't occur and he would have most definitely not stayed or signed with us even if we were to offer him a deal.
If the pandemic hadn't occurred, it's likely the salary cap would have continued to have gone up and it's feasible we'd have had enough space to accommodate him. Whether that would have been wise is another question. I think a five year deal wouldn't have been outlandish. It'd likely not be that great of a year this year, but a lot of deals are coming off after this season, so he'd have been signing in order to be on the team at the point on when the rest of the core continued to develop. Plus you need to consider that a lot of the young cores deals were signed with the rising cap in mind, where they start to look like excellent deals a few years down the road.
With Hall, we'd probably put out our best top two lines the team has had in ages. Currently we feel like we can put out a decent top line on nights, but the other line just isn't complete enough. I don't know how you'd run it, as we had Hall-Dvorak-Garland last season, but Garland-Schmaltz-Keller has been good this year. I think throwing the latter in and then pairing Hall and Dvorak would be the way to go. Maybe we'd still sign some one like Pitlick to play up with them, or Kessel could work out.
Regardless, Hall is a good complimentary piece, and if there had been no pandemic, I don't think it's an open-shut case of him not resigning here. I don't know that he's that keen to simply come out with the highest dollar and term in his contract despite earlier reporting.
One last point would be the possibility of Chayka still being here. Maybe without the possibility of him taking himself out of the team bubble, and the lack of financial losses from the pandemic would have allowed Meruelo and him to smooth things over better, as unlikely as that may sound, and thus being the GM who acquired Hall, he might be more likely to put forth the effort to retain him. Plus something about egos or whatever it is some seem to think actually guides the higher ups on teams, but this has been enough postulating on alternative timelines.
