Grading the draft class

It's become part of the every NFL Draft: the post-draft grades. Draft experts assign teams grades based on how they think they did in the draft.

Yes, no one really knows right now because the players haven't even played a down in the NFL. But in the spirit of things, we thought we'd highlight some of the reaction to the Vikings draft class. Here's a sample:

Grade: B+

Full disclosure: I am higher on Christian Ponder than most, so if you're thinking I'm going to knock them significantly for their perceived "reach" of him at No. 12, you're wrong. I will certainly admit that the No. 12 overall pick higher is higher than a quarterback coming off two arm surgeries should go, but the Vikings needed a passer who could play right away and Ponder is, in my opinion, the most pro-ready passer in this draft. If -- and it is a big if -- he can stay healthy, he'll prove worthy of this pick. Arm-strength, intelligence and mobility are not questions, in my mind. The Vikings found solid talent throughout the rest of the draft, as well. The selection of Notre Dame tight end Kyle Rudolph was a surprise considering the emergence of Visanthe Shiancoe. Versatile defensive lineman Christian Ballard (4th round), competitive cornerback Brandon Burton (5th) and developmental center Brandon Fusco (6th) highlighted a busy Day Three for the Vikings.

Grade: B-

Questionable move: Fourth-round pick Christian Ballard failed a drug test at the combine, which says something about his head.

Third-day gem: Fifth-round pick Brandon Burton was a player who some thought could go in the third round. He's a bigger corner who fills a need in Minnesota.

Analysis: I love Ponder, and I think getting tight end Kyle Rudolph in the second round also was a good move. The rest of the draft could be good, particularly if Ballard stays out of trouble.

Grade: C+

Grade: C+

Analysis: The Vikings failed to address their weak offensive line until the sixth round, which was a big mistake. They will have to look toward free agency to improve in that area on offense.

Grade: C-

What I liked: Tight end Kyle Rudolph in the second round. He started as freshman at Notre Dame, has great size (6-6, 259), nice hands and good blocking skills. Paired with Visanthe Shiancoe, he gives the Vikings a potentially great tandem in 2011.

What I didn't like: Christian Ponder. The Vikings clearly need a "quarterback of the future" after the tragically failed Brett Favre experiment of the past two years. Just not sure Ponder is the answer. Look at the list of NCAA leaders in any major passing category last year. Call me when you reach Ponder. When the phone doesn't ring, I'll know it's you.
The Vikings struggled badly in pass protection last year, too, but didn't draft O-line until the sixth round.

Their draft depends on Christian Ponder developing into a starting quarterback they can win with. If he doesn't pan out, they will regret not taking Nick Fairley or Robert Quinn.
