I don't understand the Ian Scott pick at all.
Dude put up a cumulative 0.895 sv% in 126 games in the WHL (0.894 sv% in 76 games prior to being drafted). He also is only 6'3, which doesn't make him appealing size-wise.
1) 6'3" or 6'4" is very appealing size-wise.
2) He played on a terrible team the first time, and a bubble playoff team the second time. In both cases, he played on defenses that gave up a lot of high quality chances. That does not do well for his save percentage.
3) He played pretty well today. He made some good saves. Giving up 6 goals is never good, but 5 of them were really out of his control. 1st one he was piled on and he really covered the puck but the ref did not whistle it. 3 of them were clean breakaways/odd-man rushes or shots from the slot that would be tough for any goalie to save every time. He did save a few just like that in the game. The 4th one was a really good screen that I believe got tipped or deflected so he had no chance on that one either. Ottawa's goalies were far worse than Scott.
Based on what I saw, almost everyone had good and bad moments. Liljegren looked great, but he gave up some bad opportunities. Sandin was shutting down guys like crazy, but the times he was not able to ended up costing the Leafs a goal. PK was pretty strong, but they still gave up a few goals. A lot of the offense was putting up opportunities but could not always capitalize. Scott made some great saves, but also gave up a weak one and 6 goals overall. All in all, I think the Leafs outplayed the Sens but beat themselves by handing them too many good chances and not capitalizing enough on their chances either.
