When the Capitals began their search for a free-agent goaltender to back up Braden Holtby, they had several factors to consider. Should they go with an established veteran like Tomas Vokoun, who had familiarity with the Capitals as a former player and with their new coaching staff, for whom he had played in Nashville? Should they sign a future Hall of Famer like Martin Brodeur, who helped revolutionize the position with his stickhandling ability but was in search of more playing time? Or, should they turn to someone who came with a less costly price tag and posed less of a threat to Holtby? “We talked about that a lot,” Caps general manager Brian MacLellan said after signing Justin Peters to a two-year, $1.9 million contract. “A lot of it was we wanted to send the right message to Holtby. “We want Holtby to be our guy and we want him to be supported by a good backup. Peters is a good backup in our mind and he has some upside, too. He’s 28 years old, he’s still a young guy. He’s a good teammate, he gets along with the No. 1 guys he’s played with, so we thought it was a match that way. “I mean, if you bring in an older, experienced guy it’s going to cost us more money and it might have been a little more pressure on Holtby. We wanted to send a message to Holtby that he’s our No. 1 guy.”
