The second episode of “Hard Knocks” started with Seahawks pass rusher Derick Hall being admonished by coach Mike Macdonald with a few choice words along the way. In between, the second week of the HBO series was rather … dry. You can (complain) all you want but it turns out I’m running the (expletive) practice,” Macdonald said. This week, Emmanwori graduated out of the boot to the training room and eventually a pool as he continued his recovery from ankle surgery. The episode aired on the day the team announced Emmanwori passed his physical, another key step in his return.
