In the world of dynasty fantasy football, offseason strategies can be just as important as in-season play. It's key to evaluate players whose value may be peaking, especially running backs as they have fluctuating roles. This offseason, five notable backs stand out as potential sell-high candidates. Kyren Williams of the Los Angeles Rams has seen his stock rise after a strong season, but concerns about his long-term opportunity exist with Blake Corum looming. Meanwhile, James Cook of the Buffalo Bills had a breakout campaign, leading the NFL in rushing touchdowns, yet questions about sustainability linger due to a likely revamp in the receiving corps.

David Montgomery, a key player in the Lions' backfield, also presents a sell opportunity. Despite a solid performance, his production is expected to decline with Jahmyr Gibbs emerging. Tyrone Tracy Jr. of the Giants had a decent rookie year but may not sustain his production if the team adds competition. Lastly, Brian Robinson Jr. has plateaued in his rushing yardage, and his value could diminish with potential roster changes. Evaluating these players now can provide an edge in future trades.
