Grade the Ravens' 2012 draft

Each day, we'll look at the draft for one team in the AFC North and ask you to put a grade on it. Either post a comment below or send me one to the AFC North mailbag. At the end of the week, I will post a fans' report card that includes all the division teams, along with selected commentary.

Next up is the Baltimore Ravens. Here's what they did in the 2012 draft:

Second round: Courtney Upshaw, LB, Alabama. Replacement for Jarret Johnson is eager to prove himself after watching four Alabama teammates get selected in the first round.

Second round: Kelechi Osemele, OT, Iowa State. He could make an immediate impact if he transitions from college tackle to NFL guard.

Third round: Bernard Pierce, RB, Temple. Backup for Ray Rice rushed for 3,570 career yards and 53 touchdowns.

Fourth round: Gino Gradkowski, C/G, Delaware. The younger brother of Bruce Gradkowski could be the eventual replacement for center Matt Birk.

Fourth round: Christian Thompson, FS, South Carolina State. Ran the fastest 40 time (4.5 seconds) for safeties at the NFL combine and likes to hit.

Fifth round: Asa Jackson, CB, Cal Poly. Small-school corner lacks size but can make a contribution as a returner in his rookie season.

Sixth round: Tommy Streeter, WR, Miami. Raw prospect has intriguing size (6-foot-5) and athleticism.

Seventh round: DeAngelo Tyson, DL, Georgia. He's big and athletic enough to make a team looking for depth on the defensive line.
