I'm sure they are just seeing what each guy brings to the table. Like has been previously stated they are likely trying to get some hype about the #4 pick.
On The Herd this morning they were saying that Leinart's agent is really making a push for him to go to the Jets. I'm a USC fan, so I love Leinart, but I'm not convinced about his pro career. He seems like a Carr/Harrington type to me. Superstar in college, middle of the road in the NFL. If we pick him, I'll be the first one to buy his jersey, but I won't be sold on the pick at all. I'd much rather we bring in a vet. If the CBA gets done, we're going to have plenty of cap room. Go get a McCown or Ramsey, and use our picks elsewhere.
