My point was that their job is not to continuously monitor every airplane from the marker to TD. That's what a Final Monitor is for, but they don't use those on visuals
Tower has work to do on handoff from approach and during rollout, but no real need to monitor an airplane's performance on short final...spacing is addressed further out. They were probably busy talking to other airplanes checking in, rolling out, or taxiing. The SFO tower controller handles landings on 28L/R as well as takeoffs on 1L/R.
Like I said before, if tower gets altitude alerts from approach radar they will pass that along...not all small towers have that. SFO does, but it was probably too late in this case.
I'm sure if they happened to be looking during the crucial last second they would have keyed the mike (but probably too late in this case).
