For the specifics of this issue, please read HoldenV8's post above. That sums it up nicely.
MB's game will look a whole lot better when we have some more nitty gritty forwards we now lack. Jake T needs help: Then the plain, solid, consistent, defending hooker, will have time and energy left over for more attacking runs. MB deserves our loyalty. He tackles like no one else. He cant' be everything. If it remains an issue by round 5 next year then, sure, cut his time down to 55 mins. For Right Now: Hodges should be getting 10 mins per half at least. You know it makes sense, to everyone except the coach.
