What would constitute a successful NFL draft for the Dallas Cowboys?

According to Washington Post contributing writer Jeff Dooley, it would feature defensive players being selected with the first three picks and a quarterback taken in the seventh round.

Like many mock drafts (you can find 10 separate ones from NFL draft experts all over the country right here), Dooley has the Cowboys taking defensive back Jalen Ramsey at No. 4.

Rounds two and three of a Cowboys' dream haul would include defensive end Emmanuel Ogbah and defensive tackle Sheldon Day.

SportsDay special contributor Bob Sturm evaluated Ogbah's game in an extensive post, which can be found here. Sturm liked and didn't like parts of the Oklahoma State DE's game.

Liked: He is a very explosive player who is willing to battle hard throughout a play - regardless of how much attention he is getting. He runs down plays from behind and is able to get around the corner from both the LDE and the RDE.

Didn't like: There will be some questions about his strength as a stout DE on the strong side as he can get moved out of the way a bit and appears to prefer to be the penetrator rather than the stand-your-ground type of guy against the run. But, the big issue that is a legitimate concern from NFL teams is whether or not he has a high NFL ceiling.

Here's what Dooley had to say about Day:

"[H]is production was excellent in 2015, earning the second-highest grade among interior defensive linemen (behind only Oregon's DeForest Buckner, a likely top-10 pick) and performing equally well as a run defender and as a pass-rusher," Dooley said. "Day might be limited to a role as a 3-technique defensive tackle in the pros, but that makes him an excellent fit in the Dallas defense. Day can be a disruptive force in the running game and in getting after the quarterback. The combination of Day, Ogbah and Ramsey would provide an immediate upgrade for a defense in need of one."

In four years at Notre Dame, Day played in a total of 34 games racking up 141 total tackles. He had 32 tackles for a loss, 7.5 sacks and eight pass deflections. His best year statistically was his senior year where he had 15.5 tackles for a loss and four sacks. He also forced two fumbles.

As far as the quarterback position is concerned, Dooley doesn't have the Cowboys drafting one until their last selection, which is the 217th pick overall. Dallas would be taking Bowling Green's Matt Johnson.

"Yes, the Cowboys could certainly consider taking a successor to Romo earlier than this, but in this class we don't see much of a difference between the QBs projected to go in the middle rounds than those that could at the end of the draft or become undrafted free agents," Dooley said. "Johnson is undersized for the QB position at the NFL level, at roughly 6-feet tall, but he put up outstanding numbers in our college database last season, earning the top overall passing grade in the class and consistently demonstrating an ability to make difficult downfield throws."

According to sports-reference.com, Johnson appeared in 37 games in four years at Bowling Green completing 665 of 1,0002 passes for 8,846 yards and 73 touchdowns. He only appeared in one game during his junior year after breaking his hip in the first game of the season.

SportsDay's Jon Machota's full mock draft looked a little different. He had the Cowboys taking Ramsey at four, but differed after that.

Machota had the Cowboys taking Alabama running back Derrick Henry in the second round and had Dallas addressing its quarterback needs in the fourth round by taking Dak Prescott.
