With the 2020 NFL Draft having concluded Saturday, many undrafted free agents have been active over the past 24 hours. With undrafted free-agent deals coming with an increased frequency, Denver Broncos running back Phillip Lindsay tweeted out an inspiring message for those who didn't hear their name called over the past three days.

“Remember, come preseason, it doesn’t matter if your name was called in the draft or not. Everyone still has to prove that they belong in the NFL. Its free game once you touch that field, and the best players stay. #Undrafted

Lindsay knows a thing or two about being an undrafted free agent and making himself stick around. Having joined his hometown Broncos as an undrafted free agent out of the University of Colorado in 2018, he quickly became a trusted member of the backfield, amassing north of 1,000 yards and nine touchdowns in his first season.

Lindsay proved to be no one-year wonder when he again ripped over more than 1,000 yards last year, finishing with seven touchdowns while serving as the team's starting running back for all 16 regular-season contests.

The dynamic in the Denver backfield may change somewhat in 2020 with two-time Pro Bowl running back Melvin Gordon getting into the mix, but Lindsay appears content with the challenge, having fought an uphill battle to this point in his career.

Lindsay's message is prescient, as countless undrafted free agents stick on rosters every season. They may not have had the thrill of hearing their name announced, but they can still find themselves on rosters come September.
