This will be an interested draft.
Staying at #5 there are a lot of options that will be there...
OLB - Fowler (if not gone), Beasley, Ray ... even Dupree and Gregory
DL - Leonard Williams may slip but they've already done a lot to fix the DL
OL - Scherff or Flowers will be available if they really want a RT/RG, but probably too high
WR - At least one of Cooper/White should be there
Will there be a trade? Maybe someone wants White/Cooper, or Fowler/Williams slips and someone wants them. Or Mariota even drops, albeit that seems more unlikely now. And if he's there do you take him (doubtful) knowing that RG3 may be done after this year and the 2016 draft looks horrid at QB? I think there will be some deals on the table for them, even if they don't take them.
QB/Cousins trade? - Still see this as the #1 long term issue for this team, and the only way it is going to get fixed at this point is for RG3 to step up and deliver. It is ugly if RG3 fails and you look at 2016 draft and free agency. So how do you make RG3 succeed? First, you eliminate a thorn in his side. I really like Cousins, but he isn't even the #2 in Gruden's mind. So why is he here? It may not be a great pick you get back for him, but you have to take it don't you? Another team is going to want Cousins as a backup maybe for a 4th/5th rounder. He's far better than many other backups out there. It probably isn't smart to move him for personnel reasons, but I think it's smart to move him for the mindset of RG3 and even the coaches.
WR/Garcon - How do they get a big red-zone target? If they go WR in Round 1/2, where does Garcon fit? Does he move to the slot instead of Roberts? I think Garcon is a talent so I hope he stays for at least one more year. I hate to see talent go on a team that desperately needs it. But I have to think some of the better teams would be inquiring about him.
Kick Returner - Roberts was very average, and it seems they aren't going to use Jackson there much. They desperately need a breakaway threat. Will Nelson Agholor still be there in Round 2? He could help at kick returner and WR.
Later in draft, who will they get to add some talent at S/CB and OL? They need some youth at that OL position.
Nobody is going to argue with who McCloughan takes, and nobody thinks his selections are going to miraculously make the Skins a contender. But I do think will be a fun draft for Skins fans just to see what he does.
