I have Donald 1A and Barr 1B as far as who might be in our range and who I like. I like Donald a little more because Barr has a high ceiling but you are still asking a guy to go from a RB to LB to DE in three or so years and it might take him a little longer to get it all down.
Pretty much how I feel about it too.
Donald will be plug and play, IMO. Barr will take a while to adjust.
I like Barr a good bit, honestly. I just like Donald so much and the 3-tech spot is so vital in Marinelli's scheme that Barr suffers in comparison. A good edge rusher is important to Marinelli too though, so I wouldn't be too upset with Barr if Rod thinks he is a good fit.
Here is the rub for me though... If you take Donald at 16 (or in a slight trade up to around 11) then there is Crichton in round 2 that I really like a whole lot. However, if you take Barr at 16, there honestly isn't going to be a DT in the 2nd that I like very much. If you could come out of the first two rounds with Donald and Crichton, then the DL would be greatly improved.
Basically, if we take Barr at 16, then I think the earliest we get a DT would be the 3rd... and that is too late IMO. Maybe the Cowboys like someone that I don't at DT though.
Dallas is drafting well enough now that I trust them to get the right guys, but I just think moving up a few spots to ensure Donald is the right thing to do.
