sydor and/or goligoski should get the go with orpik, and let letang work with someone he will spend time with this season (eaton or gill)
While I understand your thought process, there's more that needs to be taken into account. Orpik is one half of the top pairing and he's going to (on most nights) get the most even strength minutes on D. Therrien is going to want to pair him with someone else who should be getting those sort of minutes along with him - taking personnel into consideration, Letang is the obvious choice.
Putting Goligoski with Eaton then makes the most sense; having a bit of a safety net for Goligoski's inevitable defensive deficiencies. And then Sydor with Gill. Though, the lack of speed on that pairing - much like the Gill/Scuderi pairing - does give me a little pause but they're the 3rd pairing so they shouldn't be getting as many ES minutes anyhow.
Since MT stuck with the same pairings in practice today as he used last night, I'd say he's satisfied with things at the moment.
