The San Francisco 49ers have parted ways with a couple of important players this offseason such as DeForest Buckner and fellow running back Matt Breida, and yet another breakout player could be moving on the from the reigning NFC Champions in the near future. On Wednesday, Raheem Mostert's agent, Brett Tessler, took to Twitter to inform the public that there had been months of unproductive talks with the 49ers about fairly adjusting Mostert's contract, and that they had requested a trade. Tessler said it was "disappointing" that it would come to this for a player who led all NFL running backs in yards per carry last season and helped San Francisco to Super Bowl LIV.

Last offseason, Mostert re-signed with the 49ers on a three-year, $8.7 million deal, but clearly his value went up after what he was able to accomplish during the 2019 season. Just last week, Matt Barrows of The Athletic reported that the 49ers had discussed extensions with Mostert as well as wide receiver Kendrick Bourne this offseason, but there was no word on how those talks had gone. For Mostert, at least, the talks were apparently bad enough for him to feel a change of scenery was needed. According to Ian Rapoport of the NFL Network, Mostert simply wants to be paid like the other running backs on the rosterTevin Coleman makes $4.55 million in 2020, and that's where Mostert would like to be. 

The former undrafted free agent led the 49ers in rushing yards last year with 772 and set a franchise record for most rushing yards in a single game when he went off for 220 yards and four touchdowns against the Green Bay Packers in the divisional round of the playoffs. Mostert evolved into one of the primary options on offense as the 2019 season wore on, and he rushed for a total of 336 yards and five touchdowns in three postseason games for San Francisco.

As previously mentioned, the 49ers sent Breida to the Miami Dolphins via trade during the 2020 NFL Draft. Additionally, Jerick McKinnon's future appeared to be in doubt due to recent injuries -- so many assumed the 49ers were content with running through Mostert and Coleman in 2020. That possibility is now in doubt with the former having requested a trade.
