When the Vikings' front office assembled for the NFL scouting combine last year, it was all so much simpler. They had the No. 3 pick in the draft and were a year into a rebuilding program many, after a 3-13 season, expected had a long way to go. USC offensive tackle Matt Kalil was projected to go in the top five picks of the April draft, after Stanford quarterback Andrew Luck and Baylor quarterback Robert Griffin III, an obvious fit at a position of obvious need. And after trading down a spot to select Kalil, the Vikings had the flexibility to get another first-round pick and select Notre Dame safety Harrison Smith. Those two rookies were integral parts of the Vikings' seven-win improvement in 2012, which is precisely what makes their task at this year's combine so much more complex. Coming off a playoff season with a young roster that could make another jump in 2013, the Vikings believe a good draft could push them into Super Bowl contention. But their greatest position of need -- wide receiver -- figures to occupy their time at the NFL combine this week in more ways than one as the Vikings weigh whether to give Percy Harvin a long-term contract or try to trade him. To complicate matters, they have the 23rd pick in a draft with more underclassmen (73) than any in the league's history.
