Mose Frazier Jr. was ranked as the 853rd best … best? … college player available before this year’s NFL draft. CBSSports.com apparently didn’t think much of Frazier.

NFL scouts must have ignored one of Frazier’s most significant attributes. He was Paxton Lynch’s leading and most reliable receiver at the University of Memphis. In the past two seasons, the duo connected 117 times for 1,305 yards. Lynch was named the team’s MVP in 2015, and Frazier was selected the offensive player of the year.

“Paxton and I hit it off the first time we practiced together,” Mose told me. “He knew where to find me.”

Lynch was chosen by the Broncos in the first round. Frazier didn’t get a sniff in any round.

However, the two are reunited in Denver. Frazier was one of 21 undrafted free agents, including four wide receivers, signed by the Broncos and brought to Dove Valley for rookie minicamp this weekend.

Will Frazier be the Next Great Free Agent to make the roster?

Well, there is this slight obstacle: Although the Broncos didn’t draft a wide receiver, they have 11 under contract. Five played on the Super Bowl championship team. Another, Jordan Taylor, was a member of the practice squad and the caddie for Peyton Manning during his recovery from a foot injury. Veteran free agent Devier Posey was drafted third from Ohio State by the Houston Texans in 2012 and played under Gary Kubiak.

“The Undrafteds” are Frazier, Kalif Raymond (Holy Cross), Durron Neal (Oklahoma) and Bralon Addison (Oregon).

“No disrespect to anyone else, but I’ve overcome the odds my whole life,” Frazier said. “I’ll work hard and try to get better every day, make the right decisions, run true routes, catch every pass, return punts, play special teams, do whatever the coaches want.”

Out of Whitehaven High School in Memphis, Tenn., Mose received only one scholarship offer, from Arkansas-Pine Bluff. “I was told it was a full ride. When I got there, they said I had a partial. I didn’t want to be there anymore.”

He left after one season and walked on at Memphis, where he redshirted.

In 2013 he met the Tigers’ new freshman quarterback — Lynch. They spent three years helping to lift Memphis from a 3-9 record to a school-record 19 victories from 2014-15, Memphis’ first conference championship in 43 seasons and a No. 13 national ranking last fall, which included an upset of Ole Miss.

Lynch made the all-American Athletic Conference team. Frazier was chosen to the league’s all-academic team twice. He earned a bachelor’s degree in business in 2014 and pursued his master’s last year.

And Frazier was paid while he completed his eligibility, but it’s not some scandalous situation. During the season he got a clubhouse job as a Mose-of-all-trades at a public golf course. “I sold golf balls, filled out tee sheets, cooked cheeseburgers, swept. It was $12 an hour for spending money.” Frazier played nine holes, twice.

The day after Memphis beat Mississippi — and Mose had eight receptions for 83 yards and a touchdown — he was behind the counter as usual at 7 a.m.

Frazier was given time off and a going-away party, with a cake, by the staff and the golfers before traveling to Colorado on Thursday. He will keep his job until the Broncos’ training camp in July, and hopes he will have full-time employment in the NFL this fall.

With his buddy, Paxton.

“He was the best quarterback in the draft,” said Mose, who, naturally, is biased. “He’s got an incredible arm, throws excellent passes, is mobile and smart and a great leader. And he’s really funny.”

When the Broncos analyzed every aspect of Lynch, and attended his pro-day workout, another player with soft hands and hard routes intrigued them. “They told me that if I wasn’t drafted, they wanted to sign me,” Frazier said. “I’m very happy to have this chance.”

He has a distinct advantage over the Broncos’ 10 other wide receivers. He is the only one who has caught a business pass from Paxton.

And Frazier does have at least two staunch supporters in Denver — Lynch and me.

When the 6-foot-7, 244-pound Paxton and the 5-10¾, 190-pound Mose stand next to each other, it’s reminiscent of the old newspaper comic strip characters Mutt and Jeff.

Frazier Jr. and Paige Jr. were raised in south Memphis, a tough, poverty-stricken section with shotgun-shaped houses and barbecue-rib restaurants that produced mayors, congressmen, NBA players, civil rights activists, women who became college presidents, famous musicians and Aretha Franklin. His mom and mine attended Southside High; my dad worked in a neighborhood department store, and Mose Frazier Sr. was a solid local basketball and football player.

Mose and I graduated from the same high school — albeit almost a half century separated — on Elvis Presley Boulevard just 2 miles from Graceland. Thank you, thank you very much.

Frazier chose to wear No. 17 with the Broncos. It previously belonged to quarterback Brock Osweiler.

“My story is still to be told,” said No. 853.
