Vikings and Brett Favre has quite a few problems to solve

As the season opener ended with Minnesota Vikings being beaten by the
New Orleans Saints 9-14, both the team and their starting quarterback
Brett Favre are facing a lot of problems with the
offense, which did not scored enough on Thursday night without the top
two receivers Sidney Rice and Percy Harvin. Favre did not play as well
as he did last season in and admitted that he made mistakes for
several times during the game.
"The timing was a little bit off," Favre said after the season opener
loss. "Three or four throws, I just missed. A couple of reads I should
have made differently. If I do that, I think it's a different
ballgame."
Throwing 15 for 27 passes and 171 yards as well as one touchdown,
Favre was intercepted once simply like an ordinary quarterback. Such
an ordinary performance obviously could not guarantee the team's
chance to win the Super Bowl XLV, but Favre insisted that he came back
to play his 20th NFL season as prepared as he could and things would
only go better in following weeks of the regular season.
What caused even more concerns was that Favre appeared to be much
slower than he used to be after having a surgery on his right ankle,
which was hit several times early this year in the NFC game against
the Saints. The impacts Favre's injury were so apparent that many
other teams could also take the similar approach while playing against
the Vikings in 2010 season. People just have to doubt how long Favre
could stay healthy this season while facing such threatens.
Beside concerns on Favre's durability, the Vikings' lack of their best
two receivers could also affect the whole team's effectiveness. Rice
was held out after a hip surgery and will not return until late
October, and Harvin bothered by recurring migraine headaches does not
seem ready for a starting role. At the moment tight end Vishante
Shiancoe is sharing most of the receivers' work, but it will take some
time for him to become Favre's favorite target.
Without Rice and Harvin, the Vikings will also rely more on their
running back Adrian Peterson, but Peterson is not a guy able to
improve the team's productivity. He is always effective and is also
always rival team's target and prevented from making a game-changing
run.
