I feel everyone's over evaluating.
The factor for the Vikings offence being good/poor starts and ends with the O-line.
If you look at the positions
QB - were pretty strong, love him or hate him Bradford was an upgrade, and i hope that the improved Bridgewater we were meant to of seen last season, turns up next year and pushes Sammy Sprinkles.
RB - There are arguments about this. Asiata is a good solid blocking, power back. There is question marks over Jet however, after a below par season. A season which we all were hopeful for him.
However, i still feel he has the tools to be a good 2-down back. When he is getting zero help from up front, it's hard not to feel sorry for the bloke. I'd be happy if Spielman ignored this position in the offseason and gave JET the benefit of the doubt for one more year. I have confidence in him to produce.
WR - This is by far the most exciting young group in the whole team Diggs, Thielen, Flashy, Wright, Johnson etc. This could be one of the top groups of young receivers in the NFL, we're possibly missing an old head here. Maybe a Minnesota native playing out of Arizona
TE - Rudolph. No worries here
Which leads us to the O-line. Which any Vikings fan who's sat through this season knows is our major problem. None of the minor questions raised above, can even come close to the disaster that is our O-line. It was a sub standard group at the start of the year, and the injuries made it worse. We need to use our resources (FA/Draft) wisely to completely overturn this unit.
Because to be honest looking at the rest of the O, we don't need anything nearly as bad.
We could possibly do with another LB, but apart from that, i don't see where there's any need to upgrade anywhere else.
