With his wrist injuries, Byfield had just three goals last season, boasting a measly 4.1% shooting percentage. In the previous year, he had a 12.8% shooting percentage. Assuming his career average should be somewhere in between, likely in the 10-12% range, Byfield should score plenty more goals this year just based on that fact by itself.
Similarly, Byfield may have been more hesitant to shoot the puck last year since he knew his shot was limited by his bad wrists. If he elects to shoot at a higher rate this year that is another factor that should help him find the back of the net more often. We already know the skill is there.
