Looks like you're a little shallow in starting pitching. Don't know the stats or layout of the league, but your team can definitely hit. If I were you, I'd try trading some of your bench pieces, guys like Ackley and Stanton for a SP upgrade. As of now, looking at your team I'd put your 10 keepers as follows:
With some flex for the last two spots? I'd also try to figure out who your best non-keepers are and see if you could upgrade that to someone who you would definitely keep.
Again, need some more details though
