Rod Streater and Andre Holmes have played so well of late there is no need for the Oakland Raiders to lament the one who got away.

San Diego Chargers wide receiver Keenan Allen, a contender for the NFL's offensive rookie of the year award, played at Cal, in the Raiders' backyard.

Although in need of a playmaking wide receiver, the Raiders passed on Allen three times in the NFL draft in favor of cornerback DJ Hayden, tackle Menelik Watson and linebacker Sio Moore.

Ten spots after Moore was drafted, the Chargers selected Allen at No.76 overall, and he has proved to be one of the steals of the draft with 63 receptions for 931 yards and seven touchdowns.

Once considered a first-round talent, Allen saw his draft stock plummet because of a 40-yard dash time around 4.7 seconds while coming off a knee injury. At the NFL scouting combine, there were rumors of a failed drug test.

It turned out one of Allen's tests was red-flagged because he had too much water in his system, a sign of attempting to flush or mask a potential positive test. He took another test and passed it.

"Obviously he had the injury coming out, but I knew he was a talented player and he's shown that with the way he's playing," Raiders coach Dennis Allen said.

If the Raiders feel any remorse for passing on Allen, it has been lessened by the play of two receivers who weren't drafted at all.

Streater was undrafted out of Temple in 2012 and signed with the Raiders as a free agent. Holmes was undrafted out of Division II Hillsdale in 2010, joining the Dallas Cowboys before being released. He also was cut by New England before signing with the Raiders this past offseason.

With 54 receptions for 846 yards and three touchdowns, Streater is 154 yards shy of becoming the first Raiders receiver to gain 1,000 since Randy Moss in 2005.
