Mike Rizzo is not afraid of a little risk. When he targets a player -- as he's done a few times as the Nationals' GM, whether it's Jayson Werth, Max Scherzer or now Patrick Corbin -- he's nearly always been willing to tack on the extra year or increase his bid by a small percentage to ensure he closes the deal. Corbin is just the latest such addition, and while his contract is long for any pitcher (reportedly six years, $140 million), he was the best free-agent starter available and he gives the Nats the biggest possible upgrade out there to their current roster.
