Photos of NFL.com's 101 best free agents expected to hit the market on March 10. (Note: this list includes players that were franchise tagged on Monday, March 2)
Gore has put together one of the best careers of any running back in 49ers history and, despite being 31 and entering his 11th season, hasn't showed any signs of slowing down. Gore ran for 1,106 yards in 2014, his fourth consecutive 1,000-yard season and eighth of his career. He has never fallen short of the 1,000-yard mark when playing a complete season.
4. C.J. Spiller, Bills (No. 31 overall)
Spiller is versatile but has been inconsistent in his five seasons in Buffalo. He ran for just 300 yards in 2014 and has only completed a full, 16-game season two times in his NFL career. He can step in and handle a team's return duties from day one and is a proven receiver out of the backfield.
3. Ryan Mathews, Chargers (No. 30 overall)
Despite missing half the season and accumulating less than 400 rushing yards in 2014, Mathews averaged 4.5 yards per run, the most since his Pro Bowl season in 2011. He rushed for 1,255 yards in 16 games in 2013 and has caught 30 or more passes in three of his five seasons.
2. Mark Ingram, Saints (No. 28 overall)
Mark Ingram's best days could still be ahead of him. He is coming off the best season of his career and is only 25 years old. He ran for 964 yards and nine touchdowns in 2014, catapulting him to his first Pro Bowl. Ingram is also a viable option out of the backfield; he caught 29 passes in 2014 for an additional 145 yards.
1. Demarco Murray, Cowboys (No. 9 overall)
Murray, the 2014 NFL Offensive Player of the Year, is the crown jewel of this year's free agent class. He is considered the ninth-best potential free agent in the league by NFL.com, who wrote, "Murray was a tackle-breaking monster for the first three months of the season en route to Offensive Player of the Year honors. The No. 1 concern for potential suitors isn't the benefit of the Cowboys' dominant offensive line. It's that Murray was saddled up for a back-breaking 497 touches."
