Theodore will start against Carolina on Wednesday, according to the Washington Post's Tarik El-Bashir.
Theodore and Semyon Varlamov have split the Caps' last four games, but Theo's numbers have been much better (.979 SV% and 0.50 GAA for Theo, versus .874 and 3.39 for Varlamov). Theo's certainly playing like the team's number one starter right now, but he has been known in the past to blow up at a moment's notice. In most standard fantasy formats, it's better to own both Washington goalies if you can manage it.
