Free agent quarterback Robert Griffin III is generating "mild interest" from teams as training camp begins in earnest this week, according to a report.

According to the report, there are still teams who remain intrigued by Griffin's physical skills and wonder if he is capable of regaining the form that electrified the NFL, led Washington to a playoff berth and earned him the Offensive Rookie of the Year award in 2012.

Griffin is only 27, has five years of experience and he would likely come at a bargain contract.

On the other hand, there's a reason the interest in Griffin is mild. He can't stay healthy. Griffin has never played a full season and has suffered a significant injury during each of his first five seasons in the league. The Seattle Seahawks were the only team to publicly indicate some interest in Grifduring the offseason, but no team publicly announced a visit with the quarterback.

In addition, Griffin didn't set the league on fire during his one year in Cleveland in 2016. He completed 59 percent of his passes with two touchdown passes, three interceptions and a rating of 72.5 in five starts.
