The verdict: OVERREACTION. Could it happen? Sure. Lance could take the job and run with it, especially if Garoppolo is out for an extended period of time. But Lance also could flop next week against the 4-0 Cardinals, and then the 49ers have a bye in Week 6. If Garoppolo’s injury is going to keep him out only a couple of weeks, that could mean he misses only one game. And if Lance doesn’t impress in that one game, it wouldn’t be hard to imagine Shanahan going back to Jimmy G. If Shanahan thought Lance were ready to take over by now, Lance would have taken over by now.
