Losing DeMarco Murray will obviously hurt the Cowboys somewhat, but he probably wasn't worth the price the Eagles paid him considering the devaluation of the RB position. I wish Murray the best with the remainder of his career, but the Cowboys did what was best and moved on.
Dallas has the best OL in the NFL and I fully expect the Cowboys to have one of the most successful rushing attacks in the NFL again in 2015. Darren McFadden was terrible and often injured in his career at Oakland but is still young at 26 and should have some talent and energy left to be a solid addition the the Cowboys in 2015. I expect McFadden & whichever rookie RB Dallas drafts to share starting RB duties this upcoming season. I would like to see them go defense (DB, DT, LB, DE) in the 1st-Round and maybe draft Indiana RB Coleman in the 2nd-Round of possible.
Also, I love the Greg Hardy signing. There is obviously some comtroversy there, but he is a young, elite DL that will tremendously boost the Cowboys defense. I think it was a brilliant move by Jones.
Concerning the upcoming NFL Draft, I'd like to see the Cowboys go all defensive draft picks besides maybe a RB in the 2nd or 3rd Round.
