Tre'Davious White paused briefly, letting the moment sink in.

The Buffalo Bills' first-round draft pick signed his rookie contract Thursday, instantly becoming a millionaire. Asked if he knew what his first big purchase would be, White kept his emotions in check as he talked about taking care of his family.

"Honestly, my mom, she's been renting homes my whole life," he said. "My duty is to get her in a comfortable situation, where she can call something her own. I feel like that's my job as her child – I owe it to her for all the sacrifices she made for my little sister and two brothers."

Like all rookies drafted in the first round, White's contract is for four years with a team option for a fifth. The NFL's rookie wage scale means White will earn slightly more than last year's 27th overall pick, Green Bay's Kenny Clark, whose deal was worth a total of about $9.3 million, with a little more than $7 million guaranteed.

"It hasn't hit home yet," White said after the Bills finished their third practice of the spring. "My life changed. I'm able to do some things for my mom that typically a normal guy wouldn't be able to do. Coming from the background I come from, that's a big deal. I'm very proud of myself."

White, who grew up in Shreveport, La., becomes the third of the Bills' six drafted rookies to sign a contract, joining linebackers Matt Milano (fifth round) and Tanner Vallejo (sixth round).

"My job is to focus on football. I see guys, when contracts are not done, they want to hold out," White said. "I'm a guy, I'm all about competing. I feel like my calling here is to play football. I came in to compete, learn the playbook, get comfortable around the guys. Earn everything. ... Earn the right to play along with guys like Kyle Williams, Marcell Dareus, and the other guys in our secondary.  ... I never once thought about the contract, or it's not done, or holding out or anything like that. I love the game, so I'm going to do that before anything."

White saw some first-team reps during Thursday's practice inside the AdPro Sports Training Center.

"Now that I got a couple reps and a couple sets, I'm comfortable. I know what I'm doing now," White said. "I know where my help is. I know what some of the linebackers are doing. I know what the nickel and safeties are doing. If I continue down that road of just knowing what everybody else does on the field, it'll make my job that much easier."

White credited veterans Ronald Darby and Kevon Seymour for helping with his transition.

"Man, I couldn't ask for better," he said. "Those guys have been 100-percent supportive. Kevon and Ronald, I talk to those guys. We talk after every rep. We want to know what each other is thinking and what we see."
