GTBH 1/12/20: Trades, Made and Potential

Every week, two of the Best Fans in Baseball (TM) bring you all the news and analysis you need about the St. Louis Cardinals.  New year, new Cardinals it seems, as the winter finally livened up with a trade on Thursday, sending Jose Martinez and Randy Arozarena (plus a draft pick) to Tampa Bay for top prospect Matthew Liberatore, plus another prospect in Edgardo Rodriguez and a draft pick.  Daniel (C70 At The Bat, @C70) and Tara (Birds on the Black, @tarawellman) talk about what that means for the Cardinals and the chances that it actually could make them better in 2020, much less the future.  Then they get into all the smoke around the potential of Nolan Arenado coming to St. Louis.  Does it make sense?  Are the rumored names really what the Cards are thinking of dealing?  What are the odds Nolan is manning the hot corner in Busch on Opening Day (well, that last one is 0%--the Cards open in Cincinnati)?  All that and then some!
