Jordan Davis looks like the next Wilfork to me the more I look at him. So he would be my #1 guy but I doubt he lasts to 21.
The last time I was impressed by a big defensive lineman, his name was JJ Watt. The Patriots did not draft him.
So I'm not holding out any hope that BB would ever draft a 'binky'.
Realistically, regardless of your favorite player, you have to look at guys who could actually drop to #21.
Of those guys I'm looking at CB Andrew Booth Jr, a physical but smooth corner who can play the #1 outside position to replace our free agency loss of Mr. INT JC Jackson, or WR Chris Olave to give Mac Jones a reliable 1st option in the receiver group, or a foundation piece LT like Trevor Penning to protect Mac's blindside for at least the next 5 years or so.
