It could end up being a huge miss passing on the clear DT1 , at least athletically, but they desperately needed a RT,as well, another premium position, so passing on the risk is understandable.
If you are going to gamble with a 1st round pick, you don't pass on Bijon (Possibly best player in the draft but at a lesser valued position) and Carter ( clear best DT that comes with off field risks) to draft a big step down RB just so you can draft Sam fucking LaPorta the consensus 3rd or 4th TE in a weak TE class.
If you say you weren't disappointed in The Lions first 3 picks you are either lying or football stupid. As a Bears fan,I couldn't be happier with how the Lions drafted.
