The addition of Mario Williams and a beefed-up defense to the Bills, and the Sabres drafting two highly touted centers, Mikhail Grigorkenko and Zemgus Girgensons, has increased the anticipation for a new season of Buffalo sports. But who is closer to the end game that every fan longs for? Who has a better chance of winning a championship after their offseason moves so far?

The Bills have vastly improved their defensive depth. Williams should be an impact player starting from day one. The addition of Stephon Gilmore immediatly improved the secondary, but questions remain in the linebacker, offensive line and recieving corps. Most experts believe the Bills are better this year, but do they have what it takes to make the playoffs in a competitve AFC East, let alone win a Superbowl? If not this season, are they closer than the Sabres to bringing home a championship in the next three seasons?

The Sabres have been aggressive under new owner Terry Pegula, and begin year two of a three-year plan to win the Stanley Cup. The Sabres used the draft to get bigger and better down the middle, an area that concerned team president Ted Black. Tyler Ennis has emerged as a top-line center, and with free agency opening next week, don't be surprised if the Sabres do some wheeling and dealing this summer to ship out Derek Roy, get some room on the salary cap and add a high-profile player like Bobby Ryan or Zach Parise. But are the Sabres closer to winning a championship than the Bills? It's much harder and more unpredictable to win the Stanley Cup, as the Los Angeles Kings showed this year.
