It would seem that Jon Gruden and the Oakland Raiders are discovering what Mike Tomlin and the Steelers already found out about Martavis Bryant.
The fleet-footed, 6-foot-4, 210-pound wide receiver is an athletic freak, capable of taking the tops off of opposing defenses and is a threat to take it to the house every single time the ball's in his hands.
Problem is, Bryant's also capable of disappearing for long stretches on a football field, to say nothing of his self-destructive behavior which already has him one failed drug test away from possible expulsion from the league.
Since being dealt from the Steelers on April 27 in exchange for a third-round pick, the 26-year-old has struggled to pick up Gruden's playbook in Oakland. He's even missed a few recent practices with what the Raiders are calling migraine headaches.
But there are times, like Wednesday's practice, that Bryant reminds all that he has the potential to be the best player at his position in the NFL, prompting Gruden to call Bryant "The White Tiger."
The ... What?
"I used to go to Busch Gardens in Tampa," Gruden explained to reporters at the Napa Valley Training Complex. "We call (former Buccaneers receiver Joey Galloway) the white tiger in Tampa. You go to Busch Gardens and they've got a white tiger. You go 12 times or 13 times, the white tiger was always in his cage.
"But the white tiger came out today. Bryant came out. I don't know if you get that analogy, but sometimes he comes out to play and sometimes he doesn't. It's good to see him because he's really special, like the white tiger. It's late in the day here."
Earlier in camp, Gruden said of Bryant, he is "not a good talent, he's a great talent."
In three seasons with the Steelers, the 2014 fourth-rounder had 126 receptions for 1,917 yards -- 15.2 yards per catch -- and 17 TDs. But due to Bryant's inconsistencies on and off the field, Tomlin and the Steelers were willing to part ways with the talented but troubled receiver.
Tomlin served on Gruden's coaching staff in 2002 when Tampa Bay won the Super Bowl
