Based on where they were drafted and every other consideration.
Aldon Smith...........A-
We finally drafted a pass rusher. Has unlimited upside.
Colin Kaepernick...B
I judge fledgling preseason rookie quarterbacks on how they throw the ball, not how they read an NFL defense. Throws with outstanding velocity and superb accuracy on out, crossing, slant and hitch patters. Needs more touch on the deep ball.
Chris Culliver.........B
Very good coverage throughout the preseason. Only the perfect ball, has beaten him. That's all you can really ask of 95% of NFL cornerbacks.
Kendall Hunter.......A+
He gets an "A+" because not only can he run, but he can block very well at this early stage, which is where our past preseason RB stars have failed.
Daniel Kilgore........A-
Breath of fresh air to pick up a possible future starter, this late in the draft.
Ronald Johnson.....F
He only caught one pass. He F'd up a route to make Kaep look bad.

Didn't even make the practice squad? Looks like catching footballs and snuggling with them are two different things.
Colin Jones............C+
Any player who makes the 53 at this stage of the draft, has earned at least a C. He made some plays on special teams. He really has some speed.
Bruce Miller............A
Any player who makes the 53 at this stage in the draft, playing a totally new position, catching the ball well, blocking, and competing with a veteran fullback for playing time, has earned at least an A.
Michael Person......B
Any 7th rounder who makes a team, has earned at least a B.
Curtis Holcomb......N/A
Injured before camp got started.
Demarcus Dobbs...A+
Any UFA who makes a 53, has earned at least an A. Any UFA who plays as well as Dobbs, well, A+ is as high as it gets.
Ian Williams...........A
Made the team.
Scott Tolzien..........A+
Made the team. And threw the ball well in the preseason.
