Except he might play bigger minutes and in the top 6 with some PP time on a weaker team like he was given in Arizona post trade deadline last year on a non playoff team, while playing bottom 6 minutes with no PP time on a stronger team.
If one is deciding about what path to take to put up the most points and prove themselves at the NHL level after just 26 NHL total to date, then easier competition for roster and playing time and more opportunities should also be a consideration.
Think Connor Brown scenario here.. On the Leafs he was buried down the depth chart and deemed expendable and too costly at $2.1 mil AAV for a bottom 6 player when he scored 8 goals, while now in Ottawa he is key player that plays in their top 6 and scored 21 goals last year in 56 games (which was more goals than Marner 20) and recently got rewarded with a 3 year deal $10.8 mil [$3.6 mil AAV]
He would never have gotten that deal in Toronto, and players getting that money in Toronto don't score at his level as him. That's Alex Kerfoot $3.5 mil AAV money in Toronto, and he only scored 8 goals last year for that AAV). If Bunting scored 8 goals similarly he wouldn't be inline for a $3+ mil range next contract. He would be looking over his shoulder at young players like Robertson and Amirov etc to replace him on the roster, who are younger, cheaper with more NHL potential as he is 26 years old now.
