To play some devil's advocate here with Tyson it is possible the Rams think they can train him past the hamstring issues. They're in the upper echelon with trainers I think.
And the clavicle issue could happen to anyone, that's just bad luck, falling wrong, etc.
The knee is a major concern for me, simply because he's so twitchy that it's almost as if that torque is more a threat to injure his knee joint, what with the way he moves. OBJ had the same thing, that super natural quickness in his movement, it's rare. And again for the record I'd pass on Tyson due to this and the injuries in general.
But in this class, given the mediocre nature of the other options, it is perfectly understandable if the Rams roll the dice on Tyson. And if they were to find a way to keep him healthy, his addition on top of Nacua and Adams...
