Well how exactly do you suppose the Blues are supposed to develop these prospects when they're technically Wolves property while they're in Chicago? You can't just have them go to practice with the Wolves, then go to practice with Blues-hired coaches teaching them what the Blues want, and then expect them to retain both sets of information and do what both coaches and systems want; it's rather unrealistic. This is the purpose of having an affiliate that aligns with what the NHL club wants, rather than both teams having their own agenda. There may be some leeway with how the Blues can suggest things be done in Chicago, but ultimately Chicago makes the final decisions, so if they feel their guys they hired/signed will fit their m.o., then that's what their going with. The reason why the Blues prospects over the course of their time with the Wolves had a bunch of games played is the way the AHL deals with their teams. Of the 18 skaters that dress each game, 13 of those are considered development players, 12 of which cannot have played more than 260 professional games (including euro) and 1 cannot have played 320 pro games. Technically, the Wolves can sign as many players as they want, hypothetically the entire team they decide to ice, and leave the Blues prospects in the stands. Of course there would be a lot of controversy, and admittedly the Blues have players that the Wolves just wont be able to sign who are much better than any player they'd want to get.
Before the Blues decided to part ways, I remember hearing frustration because the Blues wanted a certain type of coaching but the Wolves wouldn't budge, or at least something to that extent. They weren't taking the time to invest in the Blues players and only focused on winning (which is directly antithetical to the AHL's core message). So there are a lot of issues dealing with the Wolves. Will it be as bad as we're thinking? Probably not, but its another couple of years where we don't have sole control over how the team operates, which is increasingly frustrating when we are having a hard time developing top notch prospects like other teams.
