I would put Fuller out of that list. Smith trade was basically a show of strength to the NFL as Chiefs wanted to trade him to a good place and Fuller was a solid CB in that mix. Not sure if he was a mistake but definitely one I can live with in that scenario.
So far I think Thornhill is the only Veach prospect that worked out on either side of the ball but he seems to be good with second tier FAs. I don't think any of his flashy moves worked out though. Clark trade looks to be very bad, so far HB is just a little better than Sorensen, Watkins looks like a massive overpay, Hitchens is just barely better than Ragland. He looks to have done better with guys who are generally overlooked sort of like Dorsey on that regard. Okafor seems like a decent addition and Ogbah looks like a steal considering the price we paid. Breeland looks pretty good and we basically need Claiborne to get to that level really fast.
