Twitter is abuzz with the sound of Manny Machado trade propositions. There's no harm in that. It's everybody's right as a sports fan to come up with their own ideas for trades — no matter how crazy — and debate proposals with other fans. But not all trade ideas are equal, of course. In his recent column for The Athletic, Ken Rosenthal came up with a package for the top teams in baseball to acquire superstar infielder Manny Machado from the Baltimore Orioles. From a Cubs perspective, Rosenthal suggests a package of Addison Russell, Mike Montgomery and a prospect for Machado. Um...no. Russell-for-Machado straight up is enough to give me pause, but I can at least wrap my head around why that might make sense for the Cubs. Adding Montgomery and a prospect, however, pushes the trade over the edge into "no way" territory if all the Cubs are getting back is Machado. For starters, Machado is set to be a free agent after the 2018 season and right now, seems intent on exploring the open market. Why wouldn't he want to? He won't get a $400 million contract like Bryce Harper may be reeling in, but Machado is still one of the very best players in baseball and should be able to fetch $200 million if he so desired. Any Cubs trade for Machado would signal some sort of all-in notion for 2018 and prompt "World Series or Bust" expectations. Why would the Cubs need to go that route and feel such urgency? They're positioned to contend for at least the next three years, but the championship window is probably open longer than that.
