The first goal that ARD gave up seemed to be a case of her just being too aggressive. She got way out on the side of her net, but didn't control the puck and couldn't get back in time. That certainly fits with her typical style of play, and obviously it usually serves her well, but it certainly has the potential to be a negative in a championship setting where the other team is much more likely to capitalize on any mistake.
As far as Tiley goes, anytime you have a game where the #1 seed is shut out and the goalie blocks 40+ shots, the goalie is going to be praised as being amazing and that the other team couldn't solve her, but I have to agree with the general notion that she was solid, but she's also not the reason that Clarkson won. That's not a criticism of her, rather, I think it's just more that Clarkson's defense played great in front of her and they kept Wisconsin's offense from getting into any kind of a rhythm. The few times the Badgers did get quality scoring chances, they didn't really challenge Tiley, often shooting the puck wide or high of the net. Ironically, that is a lot like the one other game I saw Wisconsin lose, at LaBahn against Minnesota, where Peters got the shutout after facing a lot of shots, but she wasn't the reason the Gophers won that game. It's also in contrast to Wisconsin's series at Minnesota and the their tie against UMD at LaBahn, where Peters and Rooney each really did play amazing and did shut down the Badgers.
