This. Ballard has already traded a first round pick and got an additional 2nd. He had to trade out of the first round and the 2nd was the following year. I believe it was with Washington. I’m with you. I highly doubt any team will give up their 1st and 2nd or 3rd for the 15th pick.
Christian Gonzalez, who got picked last year at 18 or around there, was defensive rookie of the first month of the season before he got season ending injury.
If the evaluation is right, elite players can produce in rookie year.
But, Bradley defense demands the CBs to be conservative, ensuring not giving up big plays so not sure their impact can be assessed well. Elite players need to be given some freedom to do their best to get the best out of their instincts.
