Would thicker neck make jawline less visible?

[mirrormogger]

So I have a decently thick neck but i've been thinking of training a bit for supposedly deeper voice and barrett tier neck but i'm wondering, wouldn't the thicker neck make the jaw bone stick out less? especially from side view?

neck training 101: get 1ml jaw filler for every 30 sets of neck curls.

good luck!
