Making the leap across the transition gap--hope I don't fall into the Chasm of Lost Translation--I think what Hurst was going for is that one coach = one session = everyone gets trained the same way at the same time, but they're expected to perform very different roles on the field. Multiple coaches = multiple sessions can be going on at the same time = players get specialized training for their specific roles, no matter what that role may be.
Hurst?
