Given his $3M buyout payment for next season, I could see him taking peanuts on a one year for one more crack at a Cup. Ideally it would be to a contender with limited cap space looking for bottom 6 depth and "intangibles".
I would say Fartsmell is probably done getting sniffs (no pun intended) at a top 6 role. I don't know the particulars on usage/linemates/etc., but you have a few different shades of Scott Hartnell from 17-18:
-Start of the year (10/5 - 11/7): Averaging around 15.5 minutes a game - 15 straight games - 4G (2PP) - 3A (2PP) - (-8)
-Return after almost month long injury (12/13 - 12/27): Around 10 minutes - 7 straight games - 0G - 0A - (+2) - 27PM (2 misconducts and a fighting major)
-Return after 1 game healthy scratch (12/30 - 3/1): Around 12 minutes - 26 straight games - 8G (all ES) - 6A (all ES) - (+8)
-In and out of line-up after Fisher returned (3/4 - 4/7): Less than 10 minutes - 13 games - 1G - 2A (1PP) - (-5)
If a team is getting 12/30 - 3/1 Hartnell for $1M or less, that's a pretty good signing.
