Thought from a new guy for whatever it is worth:
As a Georgia fan, I love Amarius Mims and he's not Isaiah Wilson, who was a first round bust of the Titans, but there are some similarities. He's RT only imo, who had 8 starts for Georgia and battled multiple injuries. I don't know if you could project him inside to guard like you can with Fatanu. I'm surprised so many sites including PFF have us taking Mims when it wouldn't make sense given the extension to AJ.
I think Fatanu is going to be great and it would be nice to kick him inside until he's ready to take over for Armstead or until TA is injured. Unfortunately, Troy killed it at the combine and I don't see him getting to us at #21.
Graham Barton would be fine, especially if we could trade down, get more picks and then take the versatile Duke linemen.
I also like JPJ but think Grier has tipped his hand by signing Aaron Brewer so quickly. The idea that they can move Brewer to guard isn't realistic to me as it seems like they had a plan as soon as free agency opened and executed it.
I like the idea of drafting a replacement for TA but think the team is in win now mode and unless one of the top LT's slips I don't see them reaching for Tyler Guyton who wouldn't add as much right away as an EDGE or third WR would.
If I'm Coach McLovin' I'm probably banging the table for a speed option at WR with some size as the Dolphin offense struggled when either Waddle or Hill missed time last season.
Love AD Mitchell who was a TD machine at both Georgia and Texas and brings 4.33 speed and much more size than the guys we have. Brian Thomas offers the same size and speed. Like Xavier Worthy but the drops and the similarities to the 2 starters at WR tell me he won't be the guy at #21.
I'd be curious what the drop off in talent between picks 21 and 55 are for DT, EDGE, WR and OL. In doing a little draft prep it seems to me that the biggest drop off between rounds 1 and 2 come at EDGE and OL.
