Hound 1 in 3 in a struggling team is more than decent
Perhaps in a good league which Eredivisie is not (Ajax and PSV aside). 2 of the 3 teams that finished below Fortuna had a player scoring more, and I would hope we aren't interested in either. It would be a huge gamble for him to be the/a main striker at the start of next season.
27 players played 10+ games as a striker in the Eredivisie last season - he ranked 18th for both goals/90 and assists/90. Personally, I would say he needed to perform in the top half of players to be "more than decent for a struggling team" - I think he did OK in a bad team.
