49ers mailbag: A (different) Jets coach to watch and the most obvious trade target
Yetur Gross-Matos (knee) is out for at least a month and possibly two. And even when he’s back, he’ll have to split duties at defensive end and defensive tackle. After him, the 49ers have Sam Okuayinonu, who’s still learning the game, and Robert Beal Jr., who has yet to make any sort of impact on defense.
