There have been plenty of teams to make crucial moves this offseason, but there's one team, in particular, that's caught the eye of Deion Sanders. After adding a few players to the roster, Sanders believes the Buffalo Bills are the most improved team after NFL free agency.

Before NFL free agency got underway, the Bills went out and signed Josh Norman following his release from the Washington Redskins. Norman, who once played for the Carolina Panthers, is familiar with Buffalo's GM, Brandon Beane.

While Norman hasn't performed up to par in recent seasons, signing with the Bills could be a decision that revives his career. On the other hand, Norman gives Buffalo a formidable cornerback to pair with Tre'Davious White.

Then, on the first day of free agency, the Bills made a blockbuster trade to acquire Stefon Diggs from the Minnesota Vikings. Diggs is coming off a season where he caught a career-high 1,130 receiving yards with the Vikings. The addition of Diggs gives Josh Allen quite the receiver trio alongside John Brown and Cole Beasley.

Besides Norman, Buffalo also finalized a deal with former Panthers defensive end, Mario Addison. Even though it's not the flashiest move, Addison gives the Bills a formidable edge rusher outside of Jerry Hughes.

With Tom Brady leaving the AFC East, the other teams in the division finally have a chance to secure the division crown. Of the teams not named the Patriots, Sanders thinks that the Bills could be the next team up in the AFC East.
