...just rearranging the seats on the Titanic.
You got a better plan or is it just hope and pray from you?
There are very few good bats available this offseason in FA. Rendon is going to cash in, around 30 M AAV. Donaldson is going to get probably 25 or so AAV for 3-5 years. The only person who hits lead off with any kind of good OBP who's also a FA is Eaton.
Cubs could trade Bryant either in a package for an arm or just to re-stock the farm. That would free up about 20 M from next year's payroll. Do that and you have room to go after Rendon. Doesn't fix lead off so you still have that problem. Maybe the Cubs trade 2 yrs of Bryant to Boston for 1 yr of Betts. Because unless you do a couple of massive trades, just about anything is going to be moving the deck chairs. They could just move to re-sign Castlellanos and put out there Rizzo, Castel, Schwarber, Bryant, Baez, Contreras, Heyward, and Nico and have a good line up. Win a series line up? Probably not. Or they could sign Eaton instead and go with Eaton, Bryant, Rizzo, Baez, Schwarber, Contreras, Heyward, and Nico and get about the same results. Or sign Gardner and move Rizzo to lead off, Schwarber to #3, and bat Gardner #5.
Or they can try your "suggestion" of signing Rendon. Either you blow payroll up, which is something I'm not against if you can afford it, or you trade Bryant away to make room. Let's say the Cubs do the latter and trade him mostly for prospects. Let's also say in this fantasy off season the Cubs trade Schwarber, Russell, and other pieces to Cleveland for Lindor and Tyler Clippard. To round it off the Cubs sign Gardner for LF. Now they can put out a line up of Lindor, Rizzo, Rendon, Baez, Gardner, Contreras, Heyward, and Hoerner (playing CF). Defensively, that could be the best infield in baseball.
