Rubbish, do you have 400m of seat post showing when doing drops? How do you know he didnt drop his post to practise?
1) obviously not
2) i hazarded a guess.
just trying to help, etc.
he must be 7ft tall if that bike's the right size for him, what is it? a 22" frame?
and, looking at his bike, he rides with a saddle bag, and his pump strapped to his frame – these are good ideas, but suggestive of a novice (or at least someone didn't think 'jumps and drops' when they bought the bike).
i hear lots of people asking for advice on technique, and lots of people think their riding difficulties are their fault, and that they're a rubbish rider. But often, a set-up tweak can work wonders.
and i see lots of people riding the wrong size bike.

(no offence is meant by the saddle-bag and pump comments, i tried it like that, but everything fell off halfway down the first rocky descent)
