Lack of depth was probably the most significant reason we failed to make the playoffs last year. Seems to me fixing the most significant problem is the best way forward. Getting younger and deeper does that.
An allstar closer, two of the top starters in baseball, an allstar catcher, and no actual weaknesses at any position seems to be enough to go toe to toe with any team in the playoffs. As long as they're healthy in the playoffs I like our chances. We need the depth so they remain healthy in the playoffs and to keep us from face planting if a rash of injuries occur like they did last season.
