If Fowler becomes a FA maybe the defense looks like: Schwarber LF, Heyward CF, Soler RF. Bryant 3B, Russell SS, Baez 2B, Rizzo 1B, Contreras C. Of those eight Rizzo is the oldest and he turns 28 next summer. The offense from that line-up the next 5 years should be nasty.
My lineup would be:
Russell SS
Bryant 3B
Rizzo 1B
Schwarber LF
Baez 2B
Contreras C
Heyward RF
Almora Jr. CF
Pitcher
That is a damn good lineup both offensively and defensively. The only player in that starting lineup is Albert Almora because the Cubs could re-sign Fowler and Madden loves having Zobrist in the lineup. Either way, we're still going to have high quality talent on the bench.
The offseason should be interesting. Do they attempt to re-sign Fowler or Chapman? Maybe both? If they don't re-sign Chapman, I wouldn't mind seeing them give CJ Edwards a shot to be the closer. Also, what do they do with Arrieta and Hammel? If anything is going to look different in the near future, it is going to be the starting rotation.
