For some context, in the 15 games for Sprong since the trade:
PIT - 18GP 68 GF (so the Pens have scored double the goals in 3 more game)
ANA - 34GF 46GA
Sprong - 5G 1A 6P 2PPG 1PPA, -5
Getzlaf - 1G 6A 7P 0PPG 0PPA, -8
Henrique - 2G 5A 7P 1PPG 2PPA, -3
He isn't that far off the performance of the two centers he has primarily playing with and is pretty close to Henrique in terms of points and % of points from EV/PP. I think expectations are a bit off in this light. Was he suppose to be driving line play and outperforming his centers at 21 even though he lost a development AHL year due to mismanagement?
