I don't understand what Eaves brings to the lineup. If we're going to play offensive non-factors, which is largely what Tootoo is, then I'd prefer non-factors that kill penalties instead of taking dumb ones. So, advantage Eaves in that regard. But I'd probably rather have Miller, and Tatar over both of them. You only need 4 forwards to kill penalties, and three of them should be Z, Datsyuk, and Emmerton. I don't find Eaves penalty killing to be particularly special, but Tatar's offensive contributions in limited playing time could be.
Mmm... I think you probably want to use Z and Dats on the PK as little as possible. This is not because they are bad at it, obviously. But you would prefer to not use your best offensive players in situations that have little chance for offense. The ideal scenario is having bottom 6 forwards that are your main PKers, in my opinion.... i.e. Miller, Eaves, Andersson, Helm, Abdelkader, etc. You want to use your top six guys on the PP. But we won't have Helm, Miller, or Abdelkader tonight. I don't see how you sit Eaves.
