Small sample size, no kidding haha
Is this a cap league, curious as you mentioned you bid on him.
I don't think you need to make this decision right now, wait to see how he performs in season/playoffs. At this point I would still keep Guentz, exposure to Crosby/Malkin is a dangerous recipe.
I am not as high on Names away from Kuch and Stamkos, a lot of his early season productivity was due to being part of the hottest line in hockey
