'No one can argue that wide receiver is one of the Bills' weakest positions. The Bills' top three receivers entering the season are Sammy Watkins, Zay Jones and Andre Holmes. Watkins is a dynamic player when healthy, but a foot injury limited him in 2016. Zay Jones should be a quality addition to Buffalo's offense, but the rookie is currently dealing with a knee sprain. Holmes, Buffalo's top free agent addition at receiver, is coming off of a 14 catch campaign. There's plenty of question marks with Buffalo's top three and beyond.'
