"Michael Crabtree had to wait an extra three picks to get drafted because the Raiders passed on him last year. The 49ers receiver has waited 18 months since to show them how he really feels.

"Of course you think about it," Crabtree said of the snub with the Raiders coming to Candlestick Park for Sunday's Battle of the Bay. "Anytime someone gets picked ahead of you, you think about it."

To be clear, Crabtree doesn't have a beef with wide receiver Darrius Heyward-Bey, whom the Raiders drafted with the No. 7 overall pick in the 2009 draft. Heyward-Bey had no choice in the matter.

Crabtree holds the snub completely against a Raiders organization that didn't so much as host him on a predraft visit, much less make him the first wide receiver drafted that year.

"I'm not worried about Darrius," Crabtree said. "I'm focused on winning the game. But at the same time, I'm thinking about the Raiders."

Two Aprils ago, Crabtree was overwhelmingly considered the best wide receiver in a receiver-heavy draft class. In two seasons at Texas Tech, he caught 231 passes for 3,127 yards and 41 touchdowns.

Crabtree won two Biletnikoff Awards as the best receiver in college. Heyward-Bey was an honorable mention pick in the ACC for Maryland.

So why did the Raiders go with Heyward-Bey? Multiple sources in the Raiders organization pointed to Heyward-Bey's 4.3-second time in the 40. Crabtree did not run the 40 after having surgery on a stress fracture in his left foot."
