Kiper's Big Board, mock get final polish

The lights will be on shortly, but Mel Kiper has released his final Big Board, a list of the top 25 available prospects, leading up to tonight's draft.

Of his first board a year ago, nine of the top 10 prospects are expected to be first-round picks, and Andrew Luck is still in school.

Here's where the Big 12's talent stacked up:

No. 2: Von Miller, OLB, Texas A&M

Analysis: Miller can impact NFL games early in his career as a pass-rushing 3-4 outside linebacker, but he also has coverage skills. Heady, big-time athlete.

No. 12: Aldon Smith, DE, Missouri

Analysis: Ideal frame, athleticism to consider for 4-3 or 3-4; still developing but a ton of upside. Athletic enough with size to be versatile. Jumps off tape.

No. 14: Blaine Gabbert, QB, Missouri

Analysis: Strong arm, good accuracy, ideal size and physical skills. An underrated athlete. Had a solid but unspectacular pro day. Will go high.

He also submitted his final mock draft before the real thing tonight. Here's where he slotted the Big 12's stars.

No. 2, Denver Broncos: Von Miller, LB, Texas A&M

...if you want dynamic upside, it's hard to go wrong with Miller. ... Miller is a smart, explosive, natural pass-rusher with the speed to track down QBs and also drop into coverage, then play the run down the line. Miller is a special talent and is a common pick as the rookie who can provide the most immediate impact.

No. 7, San Francisco 49ers: Blaine Gabbert, QB, Missouri

This time, I think Gabbert lands here. While Jim Harbaugh has taken the dignified route and stated how much he wants to work with Alex Smith, I think it's pretty fair to assume the Niners will be looking for a long-term solution for their new coach. ... Like Newton, this isn't a quarterback you want starting games in 2011, but if San Francisco is patient, Gabbert is a player it can build with.

No. 11, Houston Texans: Aldon Smith, DE, Missouri

Smith represents a ton of upside for a defense that really needs to add some pass-rushing help opposite the great Mario Williams. Again, a lot of the problems in the Houston secondary started up front.

No. 30, New York Jets: Phil Taylor, DT, Baylor

Taylor is a player that holds up as that immovable anchor against the run, a guy who can eat up blocks and let the linebackers in Rex Ryan's system run free.

No. 31, Pittsburgh Steelers: Aaron Williams, CB, Texas

Williams is the classic young, talented risk-taker at the cornerback position. He has a ton of natural ability, likes to steal a look into the backfield and turn errant passes into six points going the other way. While some see him ultimately becoming a great cover safety, I think he's a got a shot to be coached into a really good cover corner.

No. 32, Green Bay Packers: Danny Watkins, OG, Baylor

This team must do more to run the ball, must do more to shore up protection and must add depth on the offensive line. Watkins is a safe pick, a guy who helps right away.
