When it comes to Sundays in the NFL, you get the best of every player that steps on to the field for 60 minutes of football.
Why expect anything less in your first practice?
Head Coach Sean McDermott didn't necessarily want to ease the new guys into the league but rather made sure the battles for success begin early in their careers.
Cornerback Tre'Davious White, the Bills first round pick from LSU, and second round pick Zay Jones found themselves going one-on-one early and often on day one of rookie minicamp.
"I thought the drafted players were solid for the first day and that's what I was looking for," McDermott said. "You watched some competition out there with Zay (Jones) and Tre'Davious (White) out there and that was good to see."
White is considered one of the most complete and NFL ready prospects. He was a four year starter with the Tigers and possesses all the traits McDermott covets in a corner.
Jones wrapped up his career at ECU as the NCAA's all-time leader in receptions with 399 catches. He was targeted 216 times this past season with the Pirates and hauled in 158, or 73 percent of the passes thrown his way.
"I want to go against the best guys that are out there," White said. "We matched up every route. Both of us got better and I feel like we continue to do that over the next couple of days, we'll be ready to roll when the vets get here."
"(White) is a hard worker and knows his stuff," Jones added after practice. "Going against somebody like that is going to prepare me for Sunday."
The two rookies will be looked upon to provide immediate impacts for Buffalo.
Jones will hopefully provide a threat opposite of Sammy Watkins, who was limited a year ago as he battled through a foot injury while also filling the void left by Robert Woods who left and joined the Los Angles Rams as a free agent.
After not picking up Watkins' fifth year option, Jones will need to prove he can be a solid No. 2 receiver and potentially slide into the top spot on the depth chart if the former first round pick isn't on the team in 2018.
White will be tasked with helping to fortify a secondary that has to replace Stephon Gilmore, who signed with the rival New England Patriots as a free agent.
Corner Ronald Darby started in each of the last two seasons, but regressed a year ago. Keyvon Seymour saw action as the slot corner and struggled at times as well.
