Lower hockey IQ and vision but, awesome puck possession (that leads nowhere). It's one thing to blame the lack of quality wingers on Eller's line but, he was still unable to get them the puck, even if it would have meant they fanned on scoring chances or missed the net by a mile when shooting.
Desharnais, by comparison, when he played on lower lines, set up at least a couple of gimme scoring chances a game that resulted in absolutely nothing because of the quality of those receiving the opportunities.
Eller was a quick, physical, N\S type player that wasn't very creative, TBH. Falsely elevating him to cult level should only be done once he's dead...
No one is elevating Eller to cult level.
DD when used in lower roles was still not used like Eller. He was never given heavy defensive assignments.
If you have lower IQ and vision offensively, that's when being paired with the right wingers matters even further.
Someone like Suzuki, he'll be able to create things regardless because he's at a couple level higher.
Someone like Eller will need the right wingers to compliment his game. He's not going to carry his line offensively. No different to Danault, he won't carry his line.
I recall Eller centering the EGG line and limiting Galchenyuk to a give and go role (to limit his role), often setting him up for nice checks from opponents.
That line worked strictly because of Gallagher.
I think that's a tad unfair to both Galch/Eller, they played their part as well.
But let's take away Galch, replace him with Tatar, and give them 17-19min of ice time, pretty sure Eller would have improved his offensive development if that's how we used him in 13-14 following up his 30/46 season.
