Just Albies after spending a 2-3 weeks in AAA to start the season. Here are the Braves current WAR ranks by positions:
C - 4th (2.2)
1B - 3rd (3.5)
2B - 25th (0.5)
SS - 22nd (0.2)
3B - 27th (-0.4)
RF - 24th (0.1)
CF - 13th (2.2)
LF - 27th (0.0)
SP - 28th (2.0)
BP 24th (0.7)
That team is a true talent 75-80 win team right now.
Albies should be able to add ~2 wins to 2B next year. Any MLB-quality guy at 3B should be able to add another 2 wins next year. I fully expect Swanson to improve by at least 1 win. I expect Teheran to bounce back, and a rotation of Folty, Newk, Teheran, Dickey and a young guy to be markedly better than the current rotation..probably 2-3 wins better. That's 7-8 additional wins.
C will probably fall back by 1-2 wins, but the rest of the roster will most likely hold steady. That leave them with 5-7 wins of improvement for 2018.
I am confident this team can win go from 75-80 wins this year to 80-85 wins next year simply by adding a competent third baseman, and allowing the rest of the roster to improve organically.
That's how rebuilds work when they aren't rushed.
