HB11 nails it on the development on Stan.
IIRC, he plays the Ovi spot on the PP... so here, he gets no reps, which limits his chances to contribute further. Last year, he was top 6 wing injury insurance, but no one got hurt. As it turned out, he should have spent the year in Hershey.
MP got lots of chances because of injury, including filling in for Nick out for an extended period. But they are different players, MP dazzles with the puck - a waterbug that is easy to notice. Stan is more the sniper type that needs proper setups.
