Hi...my name is Mike, and I'm a Vikings fan. I haven't cheered for another team for over 38 years. I also cannot fall off the wagon, as well. If I do, I'm dragged behind it until I'm pulled back up, bruised and bloody.
As for yesterday's game, they can make ANYONE look like a good QB. How about that DB play?

Ponder made some rookie mistakes, and that's what cost them the game. They pretty much gave it away.
As for needs...I think they're set with Ponder. He seems to be a much better QB than I had thought he was when they drafted him. The biggest needs of this team are DB (both safety and CB) and WR. Obviously they're set at RB with the extension of AD and having Gerhart back there. Harvin is a stud, but with the health issues he's had, they need to protect him a bit. And he needs another playmaker on the outside to compliment him. Rudolph definitely has a bright future at TE. O-line needs some help, but I don't see it as much of a pressing need as players on the outside. They're fairly well covered on the D-line. Adding some depth there would be helpful, though. As for the LBs, I have no idea what to say. Greenway is a tremendous player. EJ Henderson has played solidly, and Erin Henderson has played better than expected. Could they use another playmaker there? Yeah, but it's not needed. The DBs are a MESS. Griffin may never become the player he was on his way to being before he shredded his knees. Winfield is still a stud when he's healthy (which hasn't been often enough lately), but he's definitely on the downside of his career. Cook? HAH! Have fun in jail. Asher Allen may be a servicable nickel back, but nothing more than that. Other than that, the rest of the CBs are guys who likely won't be playing anywhere next year. Safeties...Abdullah has his moments, but he is horrendous in coverage most of the time (bad angles, poor tackling, etc.). Sanford can be OK at times. As for the rest of them on the roster...??? No idea. Raymond is a rookie who was only expected to play on special teams. Can he become a decent safety in the NFL? I have no clue.
How can they fix these issues? Obviously, they'll have a high draft choice, but which way will they go? That depends on who will be available and declare for the draft. I really don't know who the stud college players are at those positions. What free agents will be available, as well? I'd prefer to draft a WR and go the FA route to get a DB or 2, but with a top 5 pick, I don't know if there will be a WR worthy of that high a pick available.
