49ers should rest Brock Purdy
With Trent Williams resting on the bench, and Week 18 meaning nothing more than bragging rights, the Niners have zero business whatsoever starting quarterback Brock Purdy.
Purdy likely conceded the NFL MVP award to Baltimore Ravens quarterback Lamar Jackson back on Christmas Day, so that's not a factor. On the positive side, Purdy also set a new franchise record for most passing yards in a single season with 4,050. Unless he wants to make the record much tougher to reach, there's no value in him taking the field against All-Pro defensive tackle Aaron Donald and the Rams.
Assuming Donald plays, of course.
Kyle Shanahan doesn't need to mess around here. Purdy can take a seat, and the temporary reins can be handed over to the veteran backup, Sam Darnold, who's a free agent after this season and would love nothing more than to audition for his next employer in a somewhat meaningful setting.
All the while, the 49ers would ensure Purdy would get a clean and healthy path right to the divisional round.
