NL East Notes: Prado, Cuban, Madson

There’s been lots of chatter about Martin Prado and Ryan Madson this week. Prado could be traded and Madson may or may not sign a lucrative new deal with the Phillies. Here are the latest updates from the NL East…

• The Rockies aren't the only team to inquire on Prado, according to Jon Heyman of SI.com (on Twitter).
• David O'Brien of the Atlanta Journal-Constitution wonders if Mark Cuban would have interest in buying the Braves should they hit the market at some point. Just as importantly, would MLB have interest in letting Cuban buy a team? The Dallas Mavericks owner has a reputation for challenging the status quo. 
• Executives and agents are split on whether $44MM in guaranteed money is too much for Madson, according to Heyman (Twitter links). The Phillies had been nearing a four-year deal for the closer that would have included a vesting option for 2016, but there's not much optimism that Philadelphia CEO David Montgomery will approve the deal, Heyman reports.
• MLBTR’s Mike Axisa checked in on the Mets earlier today.
