Wide receiver Jeff Badet went undrafted in April, but that hasn’t hurt his confidence any.

Badet, who signed with the Vikings as a rookie free agent, ran the 40-yard dash in 4.27 seconds at Oklahoma’s pro day in March. He said on Wednesday’s first day of training camp his speed will be plain to see soon enough.

“I know I’m the fastest guy on the Vikings,” said Badet, who caught 26 passes for 400 yards last season for Oklahoma. “I’m very fast.”

Badet, who took part in the Vikings’ rookie minicamp in early May, suffered a high right ankle sprain May 22 on the first day of organized team activities and sat out the rest of spring drills. He said Vikings rookies know about his speed, but he’s anxious to show it off to veterans, who practice for the first time Saturday at the TCO Performance Center in Eagan.

“Some of the guys already know, but some of the vets, they haven’t seen my speed yet, so I’ve got to show them,” Badet said. “We were having conversations (during the spring) and the guys were saying (cornerback) Trae Waynes is fast, but guys haven’t really got to see my speed yet because I got hurt, and I’m ready to display that soon.”

Badet called Waynes, who ran the 40-yard dash in 4.31 seconds at the 2015 NFL scouting combine, the second-fastest Vikings player. Asked if he’s certain he’s faster than Waynes, Badet said, “Yes, I’m sure.”

Badet said his health is “100 percent” after being cleared by doctors Tuesday to practice. Badet knows there are things he must work on to make the Vikings’ roster, but speed isn’t one of them.
