It all begins in earnest. The Vikings mandatory minicamp commenced at TCO Performance Center this week, and the news is already spilling out regarding who is there and who is there but not practicing. Thus far, the Vikings have good numbers in attendance, including left tackle Christian Darrisaw (who injured his knee last season) taking part in individual drills. Certainly, TE Josh Oliver is there, as he inked a contract extension and becomes an important cog in the development of the Purple’s young quarterback.
