The majority of his goals in Chiacgo came from right in front of the net, easier when you have someone like Kane directing pucks there but those types of goal scorers are wildly inconsistent. Difference between Hagel and Joseph is Joseph can create plays out of nothing, Joseph's speed is an actual weapon - not just on breakaways but coming out of corners. Hagel is fast, for sure but him being so weak on the puck takes away from that since his opponent can still get there 2nd and win the battle and again, he panics with the puck alot.
Hindsight is 20/20 but could've just kept Raddysh/Joseph and throw a 1st over for Paul instead.
