In the words of Fiona Apple, "so's everything." Kidding aside, looking at his performance over the years, I wouldn't rock that boat either. If his mental picture of what he's in is that solid that even a reskinned skate occupies even an iota of awareness, I'd say ditch it. His team needs all he can give and more. I don't doubt he could fly in any skate. Prior to his NHL days he successfully rocked RibCors, RBZs, and Tacks. For whatever reason, JetSpeed is where he sticks. Maybe it was the Goldilocks combination for him, and fussing with it just compromises his flow. Best performance flow in the world? Let it be.
It looks like he tried one-piece ASiVs in preseason practices, but once the regular season rolled around, it looks like he was in his old JetSpeeds dressed as ASiVs. If you look back at the pictures you can see the same boot pattern as he usually wears--that short, almost LEGOish blocky look of JetSpeed boots--as well as a visible separate outsole, foxing, and distinct JetSpeed toe cap. He's tried original JetSpeeds skinned to appear current in previous generations, but he's never stuck with anything else for more than a few weeks. Around All-Star Weekend last year he did wear a one-piece ASiVish pair, but he switched back shortly after the All-Star Game.
Back to your original question, I haven't followed the particulars of Bauer and CCM skate evolution over the last ten years so closely, but both brands have tended back towards less stiff, especially in the facing, as they seemed to conclude they went too far with stiffness (maybe the boots were simply lasting too long?) My thought was maybe it was in attempt to head off Scott Van Horne boots. Each time Bauer and CCM softened up a bit to provide more forward flex, they stole back some players who had gone over to SVH/True boots. Hyperlites (very Makoish) have gotten a lot of former Bauer wearers back, including Berniers, Wright, and Bedard.
