A quick check on Capfriendly shows 12 teams with more than $1M of the cap left.
13) St. Louis has $2.3M left but needs to sign a backup G.
14) Flames have $2.4M left and need to sign 3 forwards. Looking like 3 league mins.
15) Canes have $3.3M. Roster is pretty much set, but depends on moves on D. A likely candidate.
16) CBJ with ~$4M. Unlikely to have the space and Tank may not want to play for them.
17) Philadelphia - $11.7M with LTIR. They definitely have the space (moreso if they trade 50% of TDA). I don't think Tank would want to sign there but he could do so and could take term.
18) NJ - $5.6M. Honestly this should be a dark horse team to do it for one year.
19) EDM -$5.6M to re-sign Bouchard and McLeod. Will have to dump salary to make that work. No.
20) NY Rangers -$6M and need to find room for K'Andre and Lafreniere. No.
21) Sharks -$6.6M. They have the space, but I don't think Tank would want to play there.
22) Sabres - $6.7M. They could do it for one year, but probably will have a shit-ton of raises to give out the next year.
23) Bruins - $7M and need to re-sign Swayman and Frederic. Unlikely.
24) Sens - $7.5M and needs at least 3F. If they trade DeBrincat, they could sign him. Otherwise, no.
25) Wild - $8.3M but needs a goalie (starting goalie unless Fleury's the guy), 2 forwards, and 2 D. Unlikely to have space.
26) Jets - $8.6M but needs to sign Vilardi, and another F. Possible, but unlikely to have much space.
27) Preds - $8.8M. Has the space.
28) Kraken -$10M but need to re-sign Vince Dunn and 1F. Could make it work.
29) Red Wings - $13.5M. Could easily afford Tank and could give him term.
30) Coyotes - Probably a no
31) Blackhawks - $18M and only need 2D. A possible team if he wants to play next to Hall/Bedard and go to a contender at the deadline.
32) Ducks - $30M but need to re-sign Zegras, Terry, 2D, and the team sucks.
TLDR, it's his choice to take a 1 year term with a playoff team, or take more term and money with a non-playoff team. I'm kinda surprised New Jersey hasn't been mentioned much. That seems like a mutual fit. He could feasibly score a lot on that high-scoring team, but maybe he is afraid of being buried with good forwards already and having to play bottom 6.
