Deadline's impact on playoff odds

Overshadowed by the looming Biogenesis suspensions, the 2013 trade deadline will go down as one of the quieter deadlines, with more rumors flying around than completed transactions. Although there no doubt will be trades in the month of August, the waiver rules guarantee that the possible names will generally be less exciting.

When going down the teams that helped or hurt their playoff odds, it's hard not to most notice the missed opportunities all around the league, with many teams doing little or nothing to improve either their short-term or long-term prospects. For each team, I've had ZiPS calculate the rest-of-season playoff odds (as of Thursday morning) for the current rosters and the rosters as constituted before July's trades.
