Some of these grading scales dont make sense...
A - clear need/upgrade
B - stable player/no change
F - because anything less than a B is a failure
Grimes - A (no arguement)
Delmas - B+ (upgrade only if he is healthy, could be an F)
Albert - A (filled a very important need, CLEAR upgrade, money is non factor)
Starks - A (best DT available, if we didnt sign him..a certain F)
Mitchell - A (upgrade over solai, price and talent)
Trading Martin for ANYTHING - A++++++++ (friggin ace ninja awesome alternate universe impossible phenomena)
