Holtby is the best option for me, I think he's the best goalie of the group, and it's pretty obvious to think that the Capitals will be a better team than the Blue Jackets. Holtby will obviously be battling for starts with his teammate Neuvirth, but I feel like Holtby is better and thus will take the majority of the starts. While Bobrovsky might get more starts than either one of the Capitals goalies, I don't like him as much as Holtby, as I'm not very comfortable with the team in front of him, talent wise I wouldn't put him above Holtby either.
For me Holtby is the best choice of the group. Number two could go either way, I think Neuvirth is safer than Bobrovsky, but I'd rather go for a homerun swing and take Bob over Neuvirth, as this is a small risk with the reward being greater than the risk.
