The first 3/4 of the first period wasn't good - but Lyon was, so, there's that. The rest of the game wasn't bad until the very end. Rangers have a game under their belt and were probably a lot more mentally prepared for a NHL game than the Sabres were.
The only fail was Quinn, IMHO, he did not look composed end the second and the entire third.
If Lyon plays like that he gives us a chance. Not sure if UPL would've fared better.
