Wonder how much these aging field turf surfaces are contributing to these types of injuries.
Note that the Bills are the only team in the NFL to use the A-Turf Titan field turf product. "A-Turf" is a company based in Cheektowaga, NY.

Buffalo likes to draft guys out of the SEC, where just about all the surfaces are grass. That said, the artificial surfaces in the NFL are much more sticky than natural grass. I'm not surprised to see these guys pulling up lame at the Ralph as often as they do. That TD catch Sammy had last season, nobody around him, but his foot stuck to the turf and he suffered a severe injury. That injury wouldn't have happened on grass.
