some teams do well by constantly stacking picks, even in middle rounds, riding the comp pick formula to sustained success (ravens/packers are the modern examples of this). its a viable formula, but does require above average drafting.
the chiefs have been pretty hit or miss in that way... we'll see what they can do with 5 extra picks. you call them mediocre, but they got a 1 and a 2. those are far from mediocre. no shot the chiefs are better off this season, but hill doesnt look like a player who will age gracefully, and he's no spring chicken. they have mahomes for 10 years and hill will start declining in a few years.
