Regarding Sawyer Bolton.....allow me to play Devil's Advocate here. My argument is distilled down to simple mathematics.
Let's assume that SB gets engaged in a fight 2-5-10 for a total of 17 minutes, 5 of which have to be killed off.
It's almost a given, that ANY player who got the 5 for fighting is numerically more important to their team, than is Sawyer.
Trade-off with virtually ANY opponent favours the Knights.
Trade-off is significantly enhanced, if his opponent happened to be key player in their offense.
His reputation does proceed him, and his on-ice presence does influence how those opposing players adapt. They tend to "keep their heads up" and are more concerned with avoiding hits, than creating offensive plays.
Now, what other player in the league with similar scoring stats, brings as much to a game ???
