I think Wilber is a solid backup but I like this move because I never want to see Cam Lawrence playing in the base defense ever again. He is good on ST, but the team clearly has a lot of candidates for the backup LB spots now in Wilber, Brinkley, Rivers (all of whom I Iike as backups/ST guys) and also Grachkar, James Anderson and Dekota Watson competing for backup spots. Between those six guys I like the competition for the backup jobs and the top three are all capable of starting a few games if Lee, McClain or Hitchens is injured.
Then at the end of training camp Cam Lawrence will be gone when the Cowboys remove his stain from the Earth and salt the ground where it stood waive him.
