I don't disagree with what you're saying. But if we are being fair, there were more than just two guys that signed in Detroit (i.e. Hatcher, Krupp) for big money who had a lot of cache (at the time). But overall, I agree with the point you're making
Kinda lousy that both times the Wings went out and splurged on a the top D on the free agent market that injuries effectively ended their effectiveness within the first season of their deals. Yeah, Hatcher came back and played for Philly for awhile, but he wasn't nearly the same guy after his knee blew up. Rafalski worked out better, but even his career ended early because of injuries.
