I... Don't understand.
I just don't know what you're proposing, or why your proposing it.
I can see that you don't want the independent Doc puling players off the pitch for HIAs, and I do know, and can prove with endless examples, that that results in players being left on the pitch when they shouldn't.
I guess that you think the doc pulling players off the pitch is a bad thing, but why? How does asking the bias doc instead of the unbiased one make the process less biased?
Sorry, maybe I'm drunk (I kinda am), maybe I'm distracted (after all, I'm trying to watch rugby), maybe I'm tired (I'm shattered). But I just don't get what you're trying to do here.
