Why don't you think Faulk would make sense?
He appears to be a very well liked guy in the room and wore a letter for 4 seasons in Carolina, which included a year as 'co-captain' where he wore the C for road games.
He leads all Blues in ice time since his arrival in St. Louis and has led the team in both total minutes and minutes per game in two of the last 3 seasons (2020/21 and 2022/23). I think Parayko is better and more important at 5 on 5 and on the PK, but Faulk contributes big minutes both on the PK and PP.
He has 4 more years left on his contract, he is frequently called on to do post-game media, and the marketing team clearly pushes him as one of the 'faces' of the team during their in-arena segments during commercial breaks. Look at the lineup of guys who will be at Blues and Brews this week: Binner, Schenn, Thomas, Parayko, Faulk, Hayes, and Berube. That's the new guy and the presumed leadership group. Faulk is included.
I expect it to be Schenn or Thomas, but I think Faulk is an obvious choice to belong in the next tier of possibilities.
