I view Danny Jansen's maximum ceiling being a Yasmani Grandal type dual threat. Both Jansen and Grandal put up similar numbers as minor leaguers, with similar iso numbers, similar k/bb rates, similar WRC+. Jansen needs to start squaring up more baseballs to reach his ceiling, but I see no way that he will be a sub .200 BABIP player forever. Both Jansen and Grandal are very good defensive catchers as well. Trading a player of this potential calibre away for a 1 year rental player is monumentally stupid. I could see him being a key piece to a trade for somebody like Yu Darvish, but the key is the need to get some control back in any trade.
