Oakland rookie WR Juron Criner shines

ALAMEDA, Calif. -- Juron Criner stole the show.

The Oakland Raiders opened their second OTA day with veterans and rookies to the media on Tuesday.

It quickly became all about Criner, a fifth-round draft pick who made one ridiculous catch after another. He caught passes from all three quarterbacks. He absolutely ruled the workout; much like 2011 fifth-round pick Denarius Moore often did in training camp last year.

Criner -- who is not a classic speed burner -- showed leaping and hands ability. He looked terrific. It was noticed by people who Criner needs to impress. Oakland starting quarterback Carson Palmer walked off the field with Criner, giving him pointers and talking business. Oakland coach Dennis Allen praised Criner.

I liked the selection of the Arizona product when he was drafted and I am sure he will make the 53-man roster with a chance to contribute as a rookie.

Still, I am hesitant to get carried away because of one spectacular workout in May. This practice is far from a training camp session. This is basically a glorified quarterback camp. It is designed for receivers to shine. But there’s no doubt Criner stood out Tuesday.

Oakland has a crowded receiver group and it needs for players to emerge. Criner’s performance Tuesday has to make you wonder if he will be poised to make a quicker move up the depth chart than originally expected.

I will be back later with more observations from the practice.
