His maxes around 170 lbs are
401 Squat, 265 Bench Press and 539 Deadlift.
Not bad at all.

It's not, to be sure, although I honestly expected he could bench into the low threes at 170. I was doing that when I was sixteen and fairly lean at that weight -- but to be fair, I was also nowhere near a 540ish deadlift and, at that point in my training, I'd never actually squatted :\
I'm also 5'7" on a good day. I was shorter when I was 16, perhaps in no thanks due to how much I used that stupid fucking Duo-Squat machine.
