Adding Nick Bjugstad and Pius Suter did a lot for the team's center depth, but how they'll be utilized is another matter.
It's no secret that the best center on the St. Louis Blues is Robert Thomas: 81 points in 70 games, and then an additional eight points in seven games in the playoffs. There is no question that he will be the Blues' top-line center as long as he's in the lineup.
Who will center the second, third, and fourth lines, however, is a wide open field.
