One of the Patriots' motivating factors rested in their plans to turn Collins into a part-time player since the team was frustrated with his lack of success against the run, multiple sources informed of the situation told NFL Network Insider Ian Rapoport.
These developments came after the team touched base with Collins' agent, Bus Cook, over the summer on a potential contract, according to Rapoport. Both sides were far apart in contract negotiations and talks were eventually shelved.
Collins grew increasingly frustrated with the team not valuing him and he was clashing with coaches, Rapoport reported. As a result, he was ready to move on and was relieved to be traded, Rapoport added.
"I'm not the type to pout about anything," Collins said about the trade Wednesday. "This is my new home. This is my focus. I'm ready."
It remains to be seen if the Browns will be able to sign the fourth-year vet to a long-term contract or if he'll test the free-agency waters this offseason.
