Don't get me wrong. Sometimes teams get crazy lucky in talent acquisition. The Cowboys getting Parsons at 12 and Lamb at 17 falls into that category.
Also, in both cases, the Jones tried to talk themselves out of the gift they received. Lamb was there and they still considered going with K'Lavon Chaisson and even Trevon Diggs instead. With Parsons, they were so devastated about losing out on the two Corners, they bickered amongst themselves, traded down at the last second, and ended up taking him at 12.
