Put Walker in there in lieu of Shamiel and it's definitely worth looking at going forward, as Lat & Thor off the bench could be a decent option with Yvan alongside. And, I'd be willing to consider that Shamiel is likely performing poorly in practice, and thus, isn't seeing much action when it matters. That seems to be a staple of Hoiberg: if you practice well, you deserve to play & (hopefully) taking that one step further, you'll play well.
