NFL Draft 2015: 1st-Round Mock Draft and Teams Most in Need of Impact Prospect

They say Rome wasn't built in a day, but at some point, a worker laid the final brick.

The construction of an NFL roster is never complete, hence the NFL draft, a necessary evil requirement for teams to make the postseason and contend for titles.

It's no surprise the best-drafting teams rest in the bottom 20. The Cincinnati Bengals are there, as are the Seattle Seahawks (before a trade), Green Bay Packers and New England Patriots.

While it can be fun to focus on the teams knee deep in a rebuild, there are several teams in need of the final brick. Whether said brick gets the team over the hump and into the playoffs or helps contend for a Super Bowl varies, but the hole in the wall is blatant.

Below, let's take a look at a mock based on need and value at each slot and highlight three teams ready to wrap up construction.

Teams Most in Need of Impact Prospect

Houston Texans

The globe shared a hearty collective laugh when Houston Texans first-year coach Bill O'Brien decided to pass on a quarterback at No. 1 in the 2014 draft, instead selecting Jadeveon Clowney.

Perhaps he knew what he was doing, though, as the Texans missed the playoffs by just one game.

Now Houston heads to 2015 with Brian Hoyer under center. The team isn't in a position to draft one of the top two quarterbacks in the class, a realization exemplified by the signing of Hoyer.

The team is in a bit of transition, though, and as John McClain of the Houston Chronicle notes, things are rather open-ended at No. 16:

With Clowney still on the road to recovery and Brooks Reed gone, linebacker seems a good fit. But the team may hope Clowney makes a full recovery and the 10th-ranked run defense makes a return from last season, if not also improves on the 21st-ranked pass defense.

After all, Hoyer needs a big-time target with Andre Johnson gone. The window for the unit is closing, too, with Arian Foster going on 29 years old and one of the league's biggest workhorses in recent years.

No matter which way the Texans decide to go, the rookie needs to make an impact right out of the gates to help in a push to get the team over the proverbial hump.

New Orleans Saints

The definition of an all-in team, the New Orleans Saints are just as desperate as the Denver Broncos out of the AFC to gun for a title before a legendary quarterback hangs up the cleats for good. 

This refers to 36-year-old Drew Brees, whose numbers dipped a bit last season as he completed 69.2 percent of his passes for 4,952 yards and 33 touchdowns to 17 picks.

To make matters a tad more confusing surrounding the franchise, the team moved on from both wideout Kenny Stills and tight end Jimmy Graham, although the front office does have two first-round selections to toy with. 

Which might be what comes to fruition, as Larry Holder of NOLA.com illustrates:

To be fair, Brees can get production out of most anyone, and the team did well to bring back lead back Mark Ingram and add C.J. Spiller as a complement.

This means the team will turn its attention to a defense last seen ranking 25th against the pass and 29th against the rush. Defensive coordinator Rob Ryan is a guru but needs an elite talent to rush quarterbacks.

Hence the chatter of a move up. Ryan getting one elite prospect to unleash all over the field will change everything for the unit.

Philadelphia Eagles

No team experienced more turnover this offseason than the Philadelphia Eagles.

The highlights, for better or worse, are moving on from LeSean McCoy and Jeremy Maclin, adding DeMarco Murray and swapping Nick Foles for Sam Bradford.

Got it all down?

It seems a lot of movement for a team coming off a 10-win season and just missing the postseason. It would explain why analysts such as Ron Jaworski aren't sold on the new-look Eagles.

"I don't think they're a better football team right now than they were when the season ended," Jaworski said, per ESPN.com's Phil Sheridan. "They're making a lot of moves projecting where this team may be, but I just don't see this team as a better team."

So where do the Eagles turn now? 

If coach Chip Kelly is content with his offensive pieces and doesn't pull off some Madden-esque trade to move up and select Oregon's Marcus Mariota, then it has to be defense. The unit ranked 15th against the rush last year and 31st against the pass, numbers perhaps exaggerated by the fact opposing teams need to take to the air more than usual to keep up with Kelly's offense.

If so, Kelly needs to find more pass-rushers and talented members of the secondary in a hurry. An ability to find a pro-ready prospect who can hold up in an onslaught of pass attempts may morph the Eagles from a question mark to a playoff contender.
