“I’m not going to sit here and say that they think they have a Brady-type story with last year’s seventh-round pick, but I do believe the 49ers’ brass thinks Purdy’s capable of giving them the highest level of quarterback play they’ve had since Kyle Shanahan arrived in 2017 . . . The Niners are working with a six-to-eight-month return-to-play timetable on Purdy, with the idea being that the timeline should be more concrete two to three months post-op (Purdy’s surgery was March 10). That means by the summer break, San Francisco should know if it’s getting Purdy back for opening day, at some point midseason or somewhere in between.”
