I think you did fine overall talent wise but you have issues with BA, ERA and probably WHIP. I'd look to make some trades to improve this without sacrificing too much. Closers go for a premium in 16 teamers so maybe before you have too big of a hole in anything you may try trading them for a bat and arm upgrade in a package deal, while keeping an eye on the WW for potential closers that pop up during the year.
