Just note along with Dee Milliner, DJ Hayden will be long gone by the Patriots are too select in the draft unless they trade up to the top half of the draft. He's had a rapid Stephon Gilmore-esque rise up draft boards among teams in the top 16 after more tape study and less red flag concerns since he was cleared medically. Reports are that some teams, and not mock draft gurus, already peg him as a superior prospect to Milliner and may end up leapfrogging him in the process. That's entirely not surprising given his overall skillset.
The main reason he wasn't rated as highly before among the mock draft community was because of his health concerns, which as stated above are now nonexistent. Don't be shocked to see him picked in the top 16, like many were when Gilmore got picked by the Bills last year. Anyone who paid close attention the Bills last season, could see that Gilmore was a vastly superior player during the latter part of the season than he was at the beginning of it as he was often times tasked with coverage on teams' #1 WR. He's a star in the making. Hayden and Gilmore are very similar to one another.
The only CB in that range in the first round that the Patriots could select is Taylor, but he too may be gone by then. It should be interesting to see how it all shapes up.
While i agree that Hayden is moving up rapidly that in no way guarantees him a high first selection, as you are suggesting. he may go high or he could still be on the board when they are picking, I'll wait until the draft shakes out, this one is too volatile to make many such "lock" claims
