It's foolhardy to read too much into preseason, good or bad, I think. A lot of teams are giving kids long looks, lines and pairings are being shifted around in an effort to find the best chemistry, players have to be at least somewhat cautious about getting hurt. I think it's wise to keep all that in mind when thinking about preseason outcomes.
That said, I'm pretty sure last night's victory means the Sabres are officially better than the Washington Capitals AND the Detroit Red Wings. In addition, lots of Sabres fans at the game seemed to feel Henrik Tallinder played really well in his first preseason action. I think only two rational conclusions can be drawn: the Sabres are winning the Stanley Cup and Hank is winning the Norris.
