If Owens is healthy the LBs will most likely be Owens(Will), Shaq(Mike) and Grace(Sam). Pinckney looks like he will backup up Owens at Will with Gordinier backing up Shaq at Mike and McCloud backing up Grace at Sam. They will all play a ton and in Diaz's defense the Sam and Mike positions are interchangeable and are both treated as inside LBs.
I know we are all ready to put the Golden era far behind but that doesn't mean that all of the kids he recruited can't play. Look at Njoku. My point is that Gordinier may be a player. Barring injury however I don't expect the kid to ever start since Shaq should be cemented into the MLB spot and I think McCloud and Pinckney have much higher ceilings.
