Buffalo Bills fans breathed a collective sigh of relief on Tuesday when the team announced that Terry and Kim Pegula had reached an agreement to become the second owners of the Buffalo Bills.

For most, simply having stable ownership committed to Western New York is enough. The Pegulas now own both the Bills and the NHL's Buffalo Sabres, so the family is no stranger to owning a professional sports franchise.

But the NHL doesn't compare to the NFL in popularity. The Pegulas will be working on a much bigger stage now. Does their experience with the Sabres tell us anything about how they will handle owning the Bills? Here are a few things that we might be able to tell so far.

1. The Pegulas are willing to spend

Not only did the Buffalo Sabres spend big in free agency during Pegula's first offseason as owner, but he has shown a willingness to spend his money to upgrade the First Niagara Center and give the fans the best game experience. The fact that Pegula was willing to pay $1.4 billion to buy the Bills is another sign that money won't be an issue under the new ownership.

2. Pegula is willing to shake things up

Since Pegula bought the Sabres in 2011, the Sabres have had three different coaches. He took some time to feel out the situation before firing longtime Sabres coach Lindy Ruff, but he was willing to move quickly when not getting the results he wanted. The Sabres are also on their second general manager since Pegula bought the team.

3. He's willing to get former players involved

Pegula grew up a Sabres fan, so he was quick to involve some legends of the organization. He made Pat LaFontaine the Sabres' president of hockey operations, though the former star stepped down after less than one complete season. This could be a good sign for Bills legends such as Jim Kelly and Thurman Thomas, who have previously been closely involved with the Bills.

4. Pegula is willing to build

The NFL may want a new stadium for the Bills now that stable ownership is in place. Those wondering about Pegula's willingness to build need to look no further than the HarborCenter, a multimillion-dollar hockey complex that will have hotels, restaurants and retail shops attached. Maybe Pegula will want to build the next Bills stadium downtown to keep everything in one area.

5. He may not be vocal

Since taking over as owner of the Sabres, Pegula has been quieter and quieter. He didn't attend the news conference when LaFontaine stepped down as president of hockey operations, and he only released a statement when firing Lindy Ruff. His wife, Kim, is a public relations professional, so whatever his reason for not speaking, it was likely well thought out. That could be something to monitor as he takes over the Bills.
