As [former?, current?] NFL quarterback JaMarcus Russell continues his comeback attempt, Bleacher Report continues to chronicle his progress in a series of video posts.
In their latest video post, Russell looks far better, physically, than he did at the outset of his comeback effort. There also seems to be a will to succeed in Russell that was lacking in his time with the Oakland Raiders.
Regardless of his physical improvement, there's still little evidence that shows that Russell can transfer his smaller size (still over 275 lbs.) onto the playing field. Russell has more to prove than simply the ability to get into semi-football shape. He has to get into shape, stay in shape, and show that he can make appropriate calls on the football field.
Considering the weak quarterback market that this season brings, it seems likely that Russell will be able to make it into someone's camp. He won't warrant much risk in terms of money, and the payoff could be huge.
From a physical skill set perspective, Russell still has a massive arm, and with good players around him, he could run a very successful, vertical offense. The key there is JaMarcus Russell, however. If he's all in mentally, his physical skills will allow him to perform on the field.
There are still issues to address with Russell outside of simply mental toughness and getting into shape. He had a tendency to miss targets in Oakland, and it often seemed as if he just didn't care. Those things will be figured out down the road. Getting into shape now should be enough for him to warrant some looks by quarterback needy teams, and if he keeps doing what he's doing, he'll likely land somewhere by the end of the summer.
