"Technique" is an amorphous concept. It's multifaceted; a player can be useless at many things, but technically brilliant at just one. We may not describe a player like that as having "good technique", but that should not diminish what they are good at.
When we talk about technique, it's usually in such general terms that it becomes almost meaningless. Most of the time it is simply short hand as to whether a player is able to manipulate the ball, within the bounds of what their position requires, to a level that elevates them above the norm. But even then, it's never particularly informative.
And as I would hope that you would agree, pace, power, and technique — in fact, any individual attributes, bar those that are contradictory — are not mutually exclusive of one another. Easily the best striker that I have ever seen was Ronaldo, and that was largely because he managed to combine (at least in his early career) the pace to get away from people, the power and strength to avoid becoming unbalanced at the crucial moments, the fantastic ability to be able to dribble at speed, and also a deadly accurate eye for goal once he was in a position to shoot.
As for Josh King, what those youtube clips do show is a very brief compendium of the type of player that he is. It can't tell you that he is a fantastic player, of course, but that very fact reveals the contradiction in your own thinking, because the quality of a footballer is defined by so much more than one attribute. If that wasn't true, youtube clips should be able to tell you much that you need to know about a player. The fact that it doesn't is direct evidence that your own, somewhat one-dimensional thinking, is flawed.
I didn't see the young Ronaldo enough sadly but Kings damn exciting and I just hope he stays fit and finds his scoring boots...but mainly yeah stays fit. Cross fingers
