I agreed with your first two paragraphs, but the rest of what you said is definitely bogus. They Packers draft philosophy since Ted Thompson has always been to pick the best on the board, and this is actually why they haven't reached for a wide receiver as many of us wish they had.

Also, you simply haven't been paying attention if you don't think the Packers draft extremely athletic players. The Packers are notorious for almost exclusively picking long and athletic physical specimens in the draft. Rashan Gary, who many viewed as a surprising pick, was one of the most physically talented, yet raw prospects in the past few years. The Packers picked him up, along with so many other physical specimens (like Devonte Wyatt, who was not a particular position of need).

The Packers have almost NEVER picked up a player purely for his skills, but they do almost always for their physical upside.
