I'm basing this mock on the theory that Andrew Luck, Robert Griffin, Matt Kalil, Morris Claiborne and Justin Blackmon are the first 5 prospects off the board and there are no trades allowed.
Round 1, Pick 6 - Riley Reiff
Overview: If we miss out on RG3 (No, not Rex Grossman The Third) it would leave us in a bad situation, in this scenario there isn't really a prospect who fills a need or is worth the 6th overall pick. If we did end up in this scenario I think our best bet would be trading back, but because I'm not predicting trades we have to make do with what we've got.
Reiff would be my pick because I think he can be a day one starter at RT, I think he needs to strengthen up a bit but that will come with time and a full NFL off-season (Or we could just make Phillip Daniels his personal trainer, and let him drink one of Laron Landry's "protein" shakes.) Another reason he offers a good value to us is he has the ability to slide over and play LT in the case that Trent gets suspended, Trent has also missed time in his first two seasons due to minor injuries.
Round 2, Pick 38 - Mohamed Sanu
Overview: This year there is a deep crop of Wide-outs, there is a possibility that Sanu could go in the late first round but there are four or five guys who could go before him, hopefully leaving him available to us in the second round. The Scarlet Knights tried to get the ball in to his hands in as many ways as possible which really showed his versatility. Just youtube the kid and you will see that he is a play-maker, something that the skins offense is crying out for.
Round 3, Pick 70 - Casey Hayward
Overview: I think Casey Hayward is going to be one of the steals of this draft, I think he could fall to us here partly due to the fact that this years CB position is packed with prospects, and partly due to the fact that he doesn't have elite size and/or athleticism. I'm not saying he's small and slow, his physical attributes are not a weakness they just aren't elite. The Redskins coaching staff had the opportunity to work with him at the Senior Bowl and they were reported to be high on him.
Round 4, Pick 102 - James-Michael Johnson
Overview: I think it's time to groom someone as the heir to London Fletcher. JMJ has great athleticism and an nfl ready body, he was a leader, a productive player at Nevada and fits in with the type of players which were drafted last year.
Round 4, Pick 109 - BJ Coleman
Overview: If we can't get our hands on a franchise quarterback, we need a developmental player. Ryan Tannehill is not a franchise quarterback and is not worth the 6th overall pick, I would draft him with our 38th overall pick but I don't think he's going to make it out of the first round.
In my opinion, BJ Coleman has just as much if not more upside but has a lower draft stock due to playing against a lower tier of competition. The dude has an absolute howitzer, good size and mobility, and has a willingness to stand in the pocket and take a hit to get a throw off. He is raw and needs time to develop but he has a lot of upside.
Round 5, Pick 134 - Winston Guy Jr
Overview: Coming into last season the Safety position looked like it would be the strongest on our team, that was until Landry's Achilles gave up and Atogwe couldn't stay healthy which forced us to rely on Dejon Gomes and Reed Doughty (which seems to happen every year.) In a draft class which is weak at safety Winston Guy is flying way under the radar in my opinion. He lined up all over the field for at Kentucky (conventional safety, strong and weak side linebacker, and as a rush linebacker.) He is athletic and instinctive and has good range to get around the field. I think he will need some time to develop but he has the tools required to be a starting safety.
Round 6, Pick 166 - Ronnie Hillman
Overview: Ronnie Hillman is a scat back who has that X-factor which I think is missing from our backfield, he is undersized and isn't an elite athlete but it doesn't change the fact that he runs like smoke through a key hole.
Round 7, Pick 198 - Jake Stoneburner
