TJ Brodie is better than Luke Schenn (imo). He has far more mobility, is a far better puck mover, can play more minutes without having a noticeable drop off in his play and does not run out of position to make a hit or block a shot. His game is much more suited to the way the game is played today. If L. Schenn were to have played ten years ago he would arguably be one of the top defenders in the game, but that just isn't the case now. Even if Brodie is not the better player today, he projects to be in a year or two.
Somewhat. Brodie QOC numbers are lower due to the fact that he played all throughout the Flames lineup (and even out of it) at times this season, whereas Luke Schenn played consistent minutes all year long. The only regular on Calgary's defense that had positive QOC numbers was Giordano, while Philadelphia had four players. This would come as a result of Bouwmeester and Giordano being heavily relied upon to play against the teams top players by Hartley, while Laviolette preferred to spread those minutes around. Brodie won't be playing sheltered minutes anymore (and certainly wasn't by seasons end).
Mikael Backlund was our best and most consistent forward when he played this season, and I don't think it was all that close. Feaster stated they project him as a strong third line center now because he has failed to stay healthy over the course of his career. It is tough to project someone who hasn't shown the ability to play a full season as a top six player. I don't think it would be wise to move him now.
