According to a report from 94WIP's Howard Eskin, the Philadelphia Eagles were serious about getting quarterback Sam Bradford locked up long-term before the start of the 2015 season.

"They were big fans of Bradford," Eskin said Monday on the Josh Innes Show. "They're not as big of fans of Bradford because obviously they will not sign him to the contract that he turned down which was about $18 million a year." Eskin went on to clarify that the offer the Eagles made to Bradford was for 4 years at $18 million per year. Eskin also reported that it was Bradford's agent, not Bradford, that ultimately influenced the turning down of the deal."

Earlier this offseason, there were reports that the Eagles wanted to sign Bradford to a contract extension. It looks like Bradford's agent decided to bet on him, but that gamble hasn't paid off so far. He has just nine touchdowns and 10 interceptions in his first seven games with the Eagles.

Bradford is set to become an unrestricted free agent after the 2015 season.
