I personally think Colorado could be in for a strong push in the second half with Landeskog/O'reilly back and EJ returning from injury as well... and Varlamov is the undisputed #1 on his team...soo I'd go with him personally.
Odds are most are gonna say Holtby, but I'm not quite comfortable with him just yet. No doubt he's taken the #1 job for now but things can change pretty fast in Washington.
