No, the Penguins team commitment to defense suffocated Detroit's offense, Fleury is being given far too much credit in this thread. The games are on YouTube, watch them if you can. Look at the final minute of game 6! Scuderi made multiple saves behind Fleury as he slid way out of position
And the Oilers to their credit are becoming more of that kind of team, but to deny MAF had nothing to do with that is just insane.
The Oilers should be given a fair bit of credit, defensively they improved a ton this season, top 5-6 in the league for GA under Knoblaugh, and very good in the playoffs even limiting teams like Dallas and Florida to not much as those series went on.
Heart too ... given the start the Oilers had (2nd worst record in the league in mid-November), being down to Vancouver multiple times (0-1, 1-2, 2-3), being down to Dallas (oh the "real" Oilers have showed up now Dallas will mop the floor with), down 0-3 in the Finals to fight back ... lets be honest a lot of teams would have quit in those situations.
MAF's a Hall of Fame goalie and was even then an All-Star level goaltender, having a goalie like that can tilt a series no doubt about it. It's a definite advantage to have a goalie like that.
