System is decent, could be really good in a year depending on their development as their best talent is in the lower levels (Delvin Perez could become a stud but he's 17). Oh would probably net a nice return considering teams are loving closers now Carpenter, Molina and depending on how good Wainwright does the first half, would all net nice returns The others that would net nice returns, would be stupid to trade (Martinez, Reyes, Piscotty, Diaz) because they could be a future core. The others are just decent players but probably not getting you anything more than b-level prospects at best. Cardinals team isn't really old, it's actually fairly young, but they don't have much in the way of a young core of position players. They have Wong who is okayish, Piscotty who's about a two win player, and Diaz who could be really good or his first year could've been a mirage. Not much. Their rotation could be really good with Martinez and Reyes anchoring it for the foreseeable future though. Depends if Martinez can take that next step and if Reyes can cut down the walks. They're about a floor 80 wins, ceiling 90 win team.
