He's playing on a new team, for 4 games, with a new coach for everyone, and with the lines all over the place due to injuries and inconsistencies. If anyone was expecting him to come in and score 40-50 points they were sadly mistaken.
I've compared Goodrow's game to that of Boone Jenner. Similar guys. Solid 2-way power forwards who have some skill and can be moved around the line-up like a swiss-army knife. That's valuable unto itself in today's NHL with COVID, injuries, etc. The deal is really a 5 year deal where he will make only $1.25m in salary in his final year after the $1.25m signing bonus is paid.
