Minnesota Vikings 2012 preview Offense QB: The Vikings will be going with the developmental project in second year quarterback Christian Ponder. With the change to a Bill Walsh-esque West Coast offensive system, Ponder accuracy should be a positive aspect in his development. HB: Adrian Peterson will lead the way in the running back corps, but look for Gerhart to spell him at times and for the occasional use of Percy Harvin as a third down back. WR: The wideouts are led by star receiver Percy Harvin, a versatile player who can play as an outside and slot receiver as well as lining up in the backfield from time to time as he did for the Gators in college. New addition Jerome Simpson should also add some athleticism and talent on the other side of Percy, allowing him to get more wide open. TE: Kyle Rudolph will take over the starter spot in his second year in the NFL, and the Vikings coaching staff is extremely high on his talent and ability. The team also picked up John Carlson in the offseason which will allow for some two TE sets. OL: The Vikings boast an okay offensive line group that isn't going to wow anybody but should be a very solid group to protect Ponder. The key to protecting the quarterback this year will definitely be the play of rookie Matt Kalil. Defense DL: The Vikings come into the year with a top notch defensively line anchored by Pro-Bowler Jared Allen. They also have an up and comer in Brian Robison and a proven DT in Kevin Williams. They only question mark will be if Letroy Guion of Fred Evans can step up in the second DT spot. LB: The Vikings linebackers are solid at the OLB spot with Chad Greenway and Erin Henderson but have some question marks on the interior with the job being a tossup between Jasper Brinkley, Tyrone McKenzie and Audie Cole CB: The corner spots feature and aging Antoine Winfield and a rag tag group of misfits and is the likely weak spot of this defense and is expected to be picked on by most every opponent. S: Mistral Raymond will get the starting job at the strong safety spot and Vikings coaches are excited for what he can bring to the table in defending both the run and the pass. The free safety spot will be going to rookie first rounder Harrison Smith who will be looked upon to play up to his full potential.
