Boyd's your typical fringe NHL'er/13th forward. On most days, he should be on the bench. (Because, hopefully, you have a better player available.) On a good day, he can come off the bench and play on the fourth line and look like a competent NHL fourth-liner. On a great day, he can be a short-term injury replacement for someone on your third line; he won't contribute positively outside of the rare skill play, but he likely won't get embarrassed and/or scored on, either. Basically, he's consistently unnoticable, for better or worse. IMO, whenever he was on the ice for the Caps, I found myself wishing the team had a better player on the ice in his place.
But there's always the chance that, under a new system/coach and with new teammates, he might become a better player?
