I hope it works also but i highly doubt it. His game is "Taylor" made for the wing.
I don't see him having the defensive awareness or the cerebral ability to be a long term solution at center, i just don't see him ever being a 2 way threat.
He has that Ovechkin mentality to keep attacking at all times, i don't think that will work at center and if he does change his game to accomodate the center position, that will likely diminish what makes Hall special which is to consistently attack defenses with his speed. I can't think of too many players leaguewide who play Hall's kamikaze style that were/are successful at center.
I hate pulling out the Messier example again... but that's somewhat the path Hall seems to be on.
A speedy power winger who gets moved to centre and shows he can be a solid playmaking centre + a scoring threat with good defensive awareness.
It's certainly a huge leap to think Hall can make the transition as well as Messier did... I don't think Hall has either the mean streak or is enough of an a-hole to be as successful as Messier
... but I don't see why Hall couldn't play centre with at least average effectiveness.
Hall was 40% on the dot his 1st 2 seasons and improved to 55% last season (in limited opportunities of course)... so he could actually do ok in that regard as well.
He has the speed to get back defensively so to be more responsible defensively than he is now on the wing isn't beyond all possibility if it's actually something he focuses on and Eakins helps instill in him.
Honestly I'd rather leave him on LW as well but to have him try the C spot and if he does ok, then to have that versatility in his game is a good asset for himself and the Oilers in the future even when he is moved back to the wing when RNH comes back.
My gut feel tells me Hall will be just as good as Gagner at centre if not better.
