I guess the Ravens are making a tough philosophical decision here...whether to protect their guys Mellette/Williams/Doss/Thompson or give the roster spot to Brown, who has done everything to earn it. I think putting Brown on the PS is far too risky a maneuver.
It's just a sticky situation because of the Streeter/Doss/Williams/Thompson/Mellette/Brown sextet, the two guys who have done the least impressing are the two highest draft picks, Doss and Streeter.
Streeter is clearly not in contention for a roster spot
So out of Doss/LaQuan/Deonte/Mellette/M.Brown, who gets the two guaranteed spots? Is there a 6th spot? Will they go with seven? Is Thompson headed to IR? Is Thompson assured a roster spot because of his impressive contributions when given a chance?
