Earlier in March, the Bills acquired veteran quarterback Matt Cassel in a trade with the Minnesota Vikings and signed quarterback Tyrod Taylor. They also have Jeff Tuel in addition to Manuel returning.
"It’s going to be open," said Ryan. "It's a competition and whoever earns the job will be the guy that’s out there," he said. "We have some talented guys and we’ll see what happens."
Manuel, a first-round pick in 2013, completed 58.0% of his passes for 838 yards, five touchdowns and three interceptions in 2014.
The Bills went 9-7 and did not make the playoffs.
