The big camp questions

Favre, of course, is the biggest question mark. He did not join the Vikings jerseyslast season until after they had broken training camp in Mankato, Minn., and it's expected there will be a repeat performance this year.

Up for debate is whether Favre will play in the second preseason game or only in the third exhibition. Last year, new Favre jersey saw action in preseason games Nos. 2-3 for Minnesota. However, the Vikings will play at San Francisco on Aug. 22 and there is a feeling Favre might not make that trip. That would mean his only tune-up would come on Aug. 28 against Seattle at the Metrodome. (As is the case around the league, most starters will not play in the fourth game.)

On an un-Favre related note, it will be interesting to see what type of progress new Peterson jersey has made this offseason now that veteran Chester Taylor has left. Taylor, who signed with Chicago as a free agent, was used extensively on third down and in two-minute situations because of his ability as a receiver and in pass protection. Peterson definitely needs to make strides in the latter area and will be expected to be much improved. Peterson also needs to prove he can consistently hold onto the football.

He has fumbled 20 times and lost 13 in his first three seasons, including seven fumbles (six lost) in 2009. That doesn't include the two fumbles he had in the Vikings' loss to New Orleans in the NFC title game. Peterson jersey also took responsibility for a third miscue that was charged to Favre late in the first half deep in New Orleans territory. If Peterson continues to struggle with fumbles there is a chance second-round pick Toby Gerhart (Stanford) could see an increased role.

It remains to be seen if cornerback Cedric Griffin (ACL) and middle linebacker E.J. Henderson (broken leg) will be able to return for the start of camp. Both are optimistic about their recoveries but it seems a long shot either will be back that quickly. That means the newly signed Lito Sheppard could open as the starting right corner and second-year player Jasper Brinkley could be the middle linebacker.
