Using the WWHWWWH formula, we can change keys and play in the box. i guess both methods will make the player learn the fretboard better. i want to get to the place in my playing where i look at a fretted string and say "thats an F#" Or i watch a guitarist play a lead riff, and i can see that he's playing his licks from the first position pentatonic box. I find it's beneficial for me, since i'm a hands on learner, to diagram it out on a chord chart, then TAB it, then play it. Takes my brain several different ways to get something from material. Thats why i like to sit in on the theory, theres always something to be learned. The kid just wants to play. I'm trying to get him to come around on the theory. To really understand this instrument, the theory must be grasped.
