The Oakland Raiders reportedly have a "massive crush" on former Fresno State quarterback Derek Carr and may trade down to acquire him in the 2014 NFL draft.  Cleveland Browns general manager Ray Farmer, meanwhile, wants to keep teams "in the dark" and will not attend Johnny Manziel's pro day.

A report from David White of the Fresno Bee is the second to indicate the Raiders want to draft Carr.

"I hear the Raiders have a massive crush on the former Fresno State quarterback, but not a No. 5 overall pick sort of crush," White wrote on Saturday.  "They're more inclined to trade down and take Carr later, which means the Vikings would have to pass on Carr at No. 8.  All (quarterback Matt) Schaub means is the Raiders don't have to take Carr or any quarterback fifth; he buys them time to groom whoever is next."

Carr finished the 2013 season with 5,082 passing yards, 50 touchdowns and eight interceptions.

While Carr's draft stock is on the rise, Manziel's stock still appears to be falling. 

Farmer, who attended the pro days for Teddy Bridgewater and Blake Bortles, told reporters he wouldn't be attending Manziel's.  He also acknowledged he wants to keep other NFL teams guessing and doesn't put much stock into pro days.

"The systems we're using are really based on keeping everybody in the dark," Farmer said at the NFL owners' meetings, according to ESPN.  "I like the idea.  You know, the more we tell everybody, the more we're at a disadvantage I think we've put ourselves at. 

"The fact that people are guessing as to where we're located, where we've been and what we're doing is a good thing.  It's a good thing in a sense when you're too visible about certain things, it becomes obvious, and the obvious is not good for us."

"I went to a lot of games and practices this fall," Farmer added, talking about attending pro days.  "I've seen them throw the ball.  I've seen them perform in a lot of ways.  So it's not about watching them throw the ball, watching the ball come off their hands.  A lot of those things have already been addressed."

The NFL draft begins on Thursday, May 8.
