Stamkos. When he was drafted, I thought he'd be a 30-35 goal scorer, tops. I was dead wrong.
Jason Zucker. Loved his speed but never thought he'd amount to anything. I thought he'd turn into a career AHLer who gets called up for injuries his entire career and would be included in a trade sometime down the line. I was very wrong. 17 goals this year and way more responsible in his own zone. He is a poor mans Zach Parise and I think he is only going to get better.
Brad Stuart. I underestimated how bad he'd be.
Flip side..
I greatly underestimated Calvin Pickard. I always figured Aittokallio would be the better of the two and Pickard wouldn't even get a cup of coffee.
What? Brad Stuart has been decent this year.
