The description of Dan Jansen sounds like he would be one of the better prospects in the system. Honestly, it wouldn't be a bad gamble to say he will be better than Pentecost if the receiving is as good as it says. Catchers that can frame and have good walk and SO rates are very valuable no matter what the arm is like. Even if he has a noodle arm it doesn't really mean much to how valuable he could be.
