Nola and Wheeler (if healthy) will be fine no matter who plays defense, as their K rates will help them. Efflin, Gibson and Suarez are good 3-5 guys, buy they pitch to contact more so that is going to stress the D. Efflin and Gibson are more ground ball guys so maybe Stott over Bohm helps them if that pans out.
Last year I said that the bullpen can't be as bad as they year before so that should improve. Umm .. oops. I'll say the same again, they don't even need a top 10 bullpen, just an average one and they should be fine. I'm hoping that they are average.
The lineup will rake, getting anything from the Moniak/Vierling CF platoon will be good. I think Stott (Harper's BFF, but that doesn't matter wink, nudge) will get ABs at SS and 3b, and probably be below average at both, but with the rest of the lineup it doesn't matter.
All in all I think the Phillies are the 3rd best team in the division, and if things break right, they could win it, but that is not the most likely scenario.
I think the Braves have the best chance to win the division, followed by the Mets and Phillies. Each team could win depending on how their season goes and all could be in the playoffs. I think will shake out something like this:
Braves: 90-95 wins
Mets: 88-92 wins
Phillies: 85-90 wins
