Olney has had us in his top 10 rotations, bullpens, and infields...
Are we a top 10 team this year?
Teams I see as definitely better:
Phillies
Braves
Yankees
Red Sox
Rays
Rangers
Angels
Tigers
Cardinals
Teams that may be better, on par, or slightly worse:
Blue Jays
Giants
D'Backs
Reds
Brewers
Dodgers
So I think the Nats have a real shot to be a top 10 team. Adding Strasburg and NatGio to the rotation (not to mention a full season from JZimm), plugging in a 1B bat while keeping Morse in the lineup, getting a better season from Werth, and better health from Z-man could add in the neighborhood of 8-10 wins in my opinion. There's also a chance that we see notable improvement from Espinosa, Ramos, or even Desmond. The bench will be better. 90 wins is not out of the question if things break right (which, granted, they rarely ever do).
