My first 2 observations;
I dont consider McKenzie and Crowder as a probables, I look at them as locks.
And I dont see who the backup center would be. I'm not assuming Bates would move to center if Morse gets hurt; that requires TWO moves; C and RG. I think Mancz has to make the 53 as backup C ,or,Ford beats out Bates at RG.
Obviously,when it comes to special teams,reserves from various position groups compete with each other. i.e. Kumerow vs. Jones vs. Gilliam
