GREEN BAY, Wis. -- Jimmy Graham will have to make a significant impact on the Green Bay Packers this season. Otherwise there’s a good chance the three-year, $30 million contract he signed last week could easily be turned into a one-year deal.

Graham agreed to a $5 million roster bonus due on the third day of the league year next March. That means the Packers could decline the bonus and make Graham a free agent again.

That’s a sizable roster bonus for a player who will turn 32 in November, and it gives the Packers an easy out if they want to move on after a year.

If that’s the case, it would turn into a one-year, $13 million deal for the veteran tight end. He received an $11 million signing bonus and will make $2 million in salary and bonuses this season.

If the Packers moved on after one year, they would have to absorb the remaining two-thirds of the signing bonus proration ($7.333 million) on their cap in 2019 -- or it could be split between 2019 and 2020 if they chose. However, they would wipe away the remaining $17 million from their future caps, so there would be a net cap savings of nearly $10 million.

Graham was one of two free agents the Packers signed last week. Contract details of the other, defensive end Muhammad Wilkerson, were not yet available.
