There's numerous examples of the Bills patching holes in the draft.
2013 - 2 high rounders on WR's when we had SJ13 and nobody, a 1st on EJ (which is okay)
2014 - Need a WR1 so Sammy trade, need an RT so Kujo, need an LB so Preston Brown
2015 - probably our best year sticking to the board, Darby was all BPA, he was not a need, but Miller sure was
2016 - woah boy. Shaq, Ragland, Washington all need picks.
