Some wondered what it would be like if Minnesota Vikings wide receiver Stefon Diggs played in another purple uniform after he shocked the football world with the first walk-off touchdown in NFL postseason history.

In the 2015 NFL draft, the Baltimore Ravens selected a wide receiver in the first round -- but it was Breshad Perriman and not Diggs, who played in the team's backyard at the University of Maryland.

Diggs' mother, Stephanie, made sure Ravens general manager Ozzie Newsome didn't forget. According to Sports Illustrated, she ran into Newsome at last year's college football national championship game and told him: "You didn't pick my son. They should fire your ass!"

In Newsome's defense, Baltimore wasn't the only team that passed on Diggs. He was the 20th wide receiver selected, falling to the Vikings in the fifth round.

But the Ravens have long struggled to draft productive wide receivers, a fact that gets underscored by not taking a playmaker who totaled 4,106 all-purpose yards an hour down the interstate.

There were legitimate red flags that scared off the Ravens and the rest of the NFL for Diggs to drop to the No. 146 overall -- which was 120 spots after Perriman. At 6 feet, Diggs doesn't have prototypical size for a receiver. He struggled with durability, missing nine games in three college seasons.

Character concerns also caused Diggs to plummet. He was suspended for three games after he made contact with an official during a pregame incident with Penn State. Former Washington Redskins general manager Scot McCloughan told Sports Illustrated that there were background issues, which he didn't go into detail about, that "made us nervous."

"It sounded like with me meeting with the coaches and me meeting with him and the scouts, the best thing was for him to maybe go somewhere else, [away] from the area," McCloughan said in October.

Diggs has flourished in Minnesota, becoming one of the NFL's most dangerous and clutch receivers. He made history in the 29-24 divisional playoff victory over the New Orleans Saints on Sunday, when he scored the winning 61-yard touchdown with no time remaining.

Since he entered the NFL in 2015, Diggs has produced 200 catches for 2,472 yards and 15 touchdowns. His receiving yards rank 18th in the NFL among wide receivers over that span and second in his draft class (behind only Amari Cooper).

In comparison, Perriman has totaled 43 catches 576 yards and three touchdowns. He was a healthy scratch four times this season.

Perriman is the latest whiff at wide receiver for the Ravens. Some of Baltimore's biggest disappointments in the first round have been wide receivers, from Travis Taylor in 2000 to Mark Clayton in 2005 to Perriman in 2015.

Out of the 23 wide receivers drafted by the Ravens, there have been no Pro Bowl players and one 1,000-yard receiving season (Torrey Smith in 2013). Over that same period, every other NFL team has drafted a wide receiver who has recorded at least one 1,000-yard season.

Newsome is considered one of the top personnel decision-makers in the NFL, although recent drafts haven't lived up to his standard. He has drafted 18 Pro Bowl players, and his 22 first-round picks have combined for 58 Pro Bowls, four NFL defensive player of the year awards, one NFL offensive player of the year award and two Super Bowl Most Valuable Player awards.

Finding a playmaker tops Baltimore's list of offseason needs, and the Ravens could take a wide receiver in the first round again. This time, they can't afford missing on a talent like Diggs.
