Inside Slant: Remaining NFL needs

The bulk of the NFL's roster-building period ended Saturday afternoon with the final pick of the 2014 draft. Teams now move into the phase of on-field evaluation via organized team activities and minicamps, with the first training camps set to open in just three months.

That makes now a good time to scour rosters and identify what light spots still remain. The list below is not intended to be an exhaustive study of all 32 teams, but it represents some of the obvious holes some teams are facing.

The Cleveland Browns are light at receiver after a tumultuous few days.

The Browns traded out of a position in which they could have taken Clemson's Sammy Watkins, and a day later, news broke that star Josh Gordon is facing a year-long league suspension. Veteran newcomer Nate Burleson recently underwent surgery for a re-fractured arm, leaving Greg Little atop the thin group remaining.

Despite a draft deep in receivers, the Browns finished the weekend empty-handed. I can't argue with many of the players they did select, especially guard Joel Bitonio at No. 35, but they had five picks in the first three rounds. They missed an opportunity.

The identity of the Houston Texans' starting quarterback, at least for 2014, is in serious question.

With a depth chart headed by journeyman Ryan Fitzpatrick, the Texans waited until the No. 135 overall pick to select Pittsburgh's Tom Savage. While Savage has many of the physical attributes NFL teams like, his multiple college transfers left him rusty last season. He doesn't seem likely to be ready to play in 2014. (His percentage of off-target throws was 24.7 last season, highest among the top quarterback prospects in this draft.)

Would the Texans really go with Fitzpatrick to open the season? Do they think Case Keenum or T.J. Yates can beat him out in training camp? Or do they think they can pry Ryan Mallett away from the New England Patriots? The final chapter of this story remains to be written.

The Minnesota Vikings helped their pass rush with linebacker Anthony Barr in the first round, but they didn't do much to address a secondary that still needs plenty of work.

Last season, the Vikings allowed 14 touchdown passes on throws that traveled at least 15 yards downfield -- the highest such figure in the league. They signed veteran Captain Munnerlyn in free agency and have former first-round draft pick Xavier Rhodes back, but otherwise their depth is thin.

Cornerbacks Kendall James and Jabari Price, selected with the Nos. 184 and 225 overall picks, respectively, can't possibly be projected to provide immediate help.

The New Orleans Saints don't have anyone who has played center in an NFL game.

The Saints like youngster Tim Lelito, who started two games at guard last season, but they did not use any of their six draft picks on an interior offensive lineman this weekend. Free agent Jonathan Goodwin could be a possibility, but Sean Payton would not comment on it when asked by reporters Saturday.

It wouldn't be unprecedented for an NFL team to open the season with an inexperienced center, but the position is critical for the Saints -- who always have prioritized interior protection for 6-foot quarterback Drew Brees.

The Detroit Lions' coverage issues remain, well, issues.

Last season, opposing quarterbacks threw 19 touchdown passes and only eight interceptions on passes intended toward wide receivers. That differential of plus-11 was tied for third-worst in the NFL.

Since then, the Lions have replaced safety Louis Delmas with veteran James Ihedigbo. Veteran cornerback Chris Houston is dealing with a toe injury, and otherwise the Lions' top cornerbacks are incumbents Darius Slay, Bill Bentley and Rashean Mathis.

The Lions did take a defensive back Sunday, but Nevin Lawson (No. 133) was the 19th cornerback selected.
