Here are some tweets from Greg Cosell:
"Bills looking to build great defense. Love Gilmore pick. Most versatile CB in draft. Can play in slot - cover, play run, blitz."
"Glenn great pick for Bills. He can play LT in NFL. I was surprised with size + talent he didn't go in 1st round."
"Not surprised Graham went off board to Bills. Not polished at all but most vertically explosive WR in draft. Dynamic speed."
"Ode to Bills fans: Graham most vertically explosive WR in draft. Both short area burst + top end speed. Cons: Small frame. Raw route runner."
"Graham's issue will be size. Very small frame. Not strong. But similarities in vertical explosion to Wallace out of college few years back."
