Johnson appears to be a bonafide starter at this point and deserved his West all-star nod. For a kid in his first full year as a starter, I think he looks like a definate keeper. Lance Frazier played well enough when he was healthy last year. I do see him as being on the bubble, a bit, but odds are he'll be the starter at the end of camp. Samuels might be worth taking a look at, but to say he is for sure better than what we already have is a bit of a stretch. The bonus with Samuels is age--he is only 24. So he is worth a look, perhaps. Is Bolden free or not? I thought he was, but the CFL site still lists him as a Bomber...? Anyway, he is 34 years old, and I doubt we will look at him.
One thing that perhaps is being overlooked is that, Aribin Justin, could concievably be moved to the half spot if he loses his job to Morgan. Bottom line is, the only secondary jobs that should be safe are Johnson and Davis. Everyone else is in a real battle.
