Jeff Ireland, Kevin O'NeillJeff Ireland has enough problems with his current roster at the moment, so he certainly doesn’t need former players making matters even worse.

Former journeyman quarterback Sage Rosenfels, who played for the Dolphins from 2002 to 2005 and again while Ireland was the general manager in 2011, didn’t exactly enjoy his second stint with the organization. He took to Twitter on Thursday to offer up some insight on the Dolphins and dish some dirt on Ireland.

Rosenfels, who spent 11 seasons with five different teams, rejoined the Dolphins in 2011 but was only on the active roster for two weeks before being placed on the non-football injury (NFI) list when he contracted mononucleosis. Once Rosenfels was healthy, though, he says Ireland refused to take him off the NFI list or release him as the GM feared Rosenfels knew too much about the Dolphins’ offense. Instead, Ireland waited until the beginning of December to cut the quarterback, leaving Rosenfels a small chance of being signed (the Vikings claimed him off waivers).

The saga left Rosenfels with a bad taste in his mouth about Ireland and a deeper understanding of just how the general manager approached his business. Rosenfels even went as far as to call Ireland the “worst GM in my career.”
