Strength won't be the issue, and it should give him the benefit of not having to have technique perfectly down to make an impact. If he can actually learn technique, then he will be an absolute force.

Put differently and more thoroughly: no technique - no impact; some technique - more impact than a player 100 lbs lighter would have with the same level of acumen; good technique - absolute beast.

No technique and some technique are a lot more likely than good technique. Maybe a 45-45-10 split; maybe that's too optimistic, and it's more like 50-45-5 or even 55-43-2. The biggest factor will be how hard he works.
