49ers importing Darnold

ESPN's Adam Schefter reports that the 49ers have reached a one-year deal with QB Sam Darnold. The quick signing tells us that San Francisco isn't sure QB Brock Purdy will be ready for the regular season. If the 49ers did expect Purdy's repaired right arm to be all good, then there would seem little reason for them to prioritize a third QB on the open market and little reason for Darnold to sign so quickly. Why settle for a locked-in No. 3 role on the first day of "legal tampering" rather than wait to see what other QB-needier teams might say. Of course, we're betting Trey Lance will open the year as the starter. The fact that Lance remains unproven heading into his third year -- and is coming off his own serious injury -- enhances the upside for Darnold. In addition to Purdy, HC Kyle Shanahan's offense has helped QBs Jimmy Garoppolo, C.J. Beathard and Nick Mullens generate good efficiency. Darnold would be interesting for fantasy if pressed into duty. That makes him stashable in deeper dynasty leagues.
