Good question. I think the Giants, Browns, Jets and 49ers are obvious spots. There could be others that I'm forgetting, or teams that could move up.
SF could go a number of ways at #13. Jeudy or Lamb could definitely be targets. Also, they now have a huge hole at defensive tackle.
It's hard to see one of those top four making it to 18 no?
I really don't think so. Here are some things that you can almost certainly count on in the top half of the first round every draft:
1) Someone's going to reach for a player that they fell in love with that they probably could have had later in the round, but they either didn't trust that they could trade back and still get him, or didn't have a trade partner. Last year this was the Raiders.
2) Someone's going to reach for a player that they fell in love with that they probably could have had a full round or so later, but they either didn't trust that they could trade back and still get him, or didn't have a trade partner. Last year this was the Giants.
3) Someone's going to reach for a position of need rather than take the BPA. Last year this was the Lions.
So. There are 4 of those top OT (Wirfs, Wills, Becton, Thomas). Let's assume THREE of those four go before pick 18. Fine.
The other top 14 players this year other than Tackles are probably going to be:
3-4 QB (Definitely Burrow, Tua, Herbert, maybe Love)
1-2 Edge rushers (Definitely Chase Young, maybe Chaisson)
1-3 WR (I feel pretty confident that Jeudy goes before 18. Maybe Ruggs? CeeDee Lamb?)
1-2 LB (Definitely Simmons, maybe Kenneth Murray)
1-2 DT (Derrick Brown**, maybe Javon Kinlaw)
1-3 CB (Definitely Okudah, maybe CJ Henderson, Jeff Gladney?)
Are all of these "maybes" going to be taken before pick 18? Of course not. Say (and I think this is low) slightly fewer than half of them are. I put eight "maybes" up there. Say three of them get picked. You're already up to 11 players taken. You only need 3 more non-Tackle players to go before pick 18.
Then you've got the other "maybes" like Xavier McKinney or Grant Delpit who could be a good fit for a team that needs a safety, and not that much of a reach.
Then you've got a team that really, really needs a center in the mid-teens and takes Cesar Ruiz, who's a borderline late first rounder/2nd rounder. A reach? Yep. Possible? Sure.
Then you've got a team like the Raiders that falls in love with AJ Epensa and absolutely HAS to have him at 12. A bit of a reach? Sure. Could they have traded down to the mid 20s and nabbed him there? Probably, but they didn't want to chance it, or nobody wanted to trade up. That's certainly possible.
Then you've got a team that absolutely, positively falls in love with one of the RBs. JK Dobbins, or DeAndre Swift, for example. And they do something bat-**** crazy and draft him in the teens.
And then there's something completely out of left field that I haven't even thought of.
Are ALL of these things going to happen? Of course not. Some of those things are absolutely crazy. But you only need a few of them to happen. Bat-**** crazy stuff always, always happens at the NFL draft. Daniel Jones goes #6 in 2019. Kolton Miller goes #15 in 2018. The Bears give up multiple draft picks to move from #3 to #2 and select...Mitch Trubisky. And again, you only need a few *slightly* unusual things to happen, and the Fins have one of those top 4 offensive tackles fall in their lap at #18.
**So, Derrick Brown. I have seen more than one mock where he falls PAST the #18 pick. If this happens, the Dolphins should absolutely, positively take him at 18. I don't care if they have the Easter Bunny at Left Tackle next year. Brown is one of the most destructive D-Line players I've ever seen, and I believe that aside from a QB, he's going to be one of the two most impactful players in the entire draft.
