Rocco Grimaldi is a fantastically talented player that most poolies know about. However, due to his lack of size and knee injury last year, he probably has fallen off the radar of many people or could be had cheaply right now. This kid has all the tools to be a very good player in the NHL. Speed, shot, passing, hockey sense, and a 'never-quit' attitude.
If he can stay healthy, I think he will put up excellent numbers in the NCAA and will then transition to the AHL where he should continue to produce. My prediction is that he will be a top-6 forward for the Panthers in 2-3 years and get a solid 65+ points per season eventually.
He could be a great pickup right now, before he goes on a tear in college (scoring tear, not knee tear, I mean!).
