If he is like Danny Stewart in his first season for the Blaze you have yourselves a damn good player. Is that type of role enough to look after an entire team though? I'm not so sure.
Judging by coaching references from those that have coached him, he will no doubt be a great locker room guy, a fans favourite and a 110% player, but for the role that he has been signed with little (any?) back-up I feel he may struggle. Of course, Thommo knows more than I ever will!!!
As for Frank, I think it would be rather unfair (for Devils fans and others) to compare him to Weller, who was a one-off, a not-long-out-of-NHL-forward-turned-defenceman who could do it all at this level.
I will however, be expecting Frank to fill Sawyer's skates and he looks more than capable of this.
