Nelson doesn't think it's because of the system.

"It's tough for me because I feel in my heart -- and this is just me -- the only reason it's happening is because of the injury," Nelson told Tim Graham of The Buffalo News.
"I feel if I was able to play last year, things would be different 100 percent. For me that's the reason why; they're not sure if I'll be the same player I've been."
Nelson, who was a go-to target of quarterback Ryan Fitzpatrick in 2011, says he's running routes a month before his rehab schedule initially planned him to.
He's understandably upset about having to part with the team that gave him his first shot as an underrated free agent in 2010, but he's rigorously preparing for what the free market could bring.
"There will be a demand for proven receivers on the first few days of free agency," Nelson said. "It probably will be a lengthy process for me."
