I'd say that there was excellent defense on about 3 of those balls, one was overthrown( I think, it's hard to say without watching the entire route), one underthrown. A receiver with strong hands and better shielding technique will catch some of those contested balls, but many will not. For all that GB has been spoiled by great QB's over the years, Vikes have been spoiled by great receivers. Not all teams are blessed as we are with the likes of Diggs, JJ, Thielen, Moss, Carter. Many teams will have drops like that, especially if the ball arrives a bit late, a bit low, a bit high, etc.
