The point is that Herbert was last gasp option when we got messed about by Orford - essentially he was all that was available for that season, and was shipped off - rightly - at the end of that season.
Gale is the guy that was chosen for the role, handed the vice captaincy and a better contract. We constantly hear about how good he is, how the team will be built around him etc.
You can't compare those two circumstances really
For that reason, I'm more disappointed with what Gale does - or doesn't do - than I ever was with Herbert.
