Nah don't think so mate. If he was it probably would of been during a game, for the last couple of minutes. In Jonah's era there were plenty ahead of him (Fitzpatrick, Z. and R. Brooke, Brown, Dowd, Jones, basically the whole forward pack, Mehrts, even J. Marshall captained early in his career). He wouldn't make a good captain anyway.
Wilson was only captain for 1 or 2 games i think (I wasn't around at the time) and that was because he was filling in while someone came back from injury. But he did start and finish the game as captain i think.
