The Vikings might want to sign Onatolu to a more cost-effective deal, with more years at less money per year.
An exclusive rights tender is a one-year offer ranging from about $1 million to $2.7 million. The NFL free agency period begins on Tuesday. The Vikings have two restricted free agents and 15 unrestricted free agents from last season's team.
Onatolu, a linebacker in his third season with the Vikings, is highly-regarded as a special teams player. He had 20 tackes last season and played in all 16 games. Onatolu played in the Canadian Football League until 2009.
