Great posts by panchester07 and heiky0711 coming from 2 very different perspectives.
Another factor that could be mentioned is age. If you look at very young players (under 13) it's usually the biggest and fastest among them tend to dominate. During puberty, between 13-18, it's mostly about skills and being technical. After that point, the best players are usually the most tactical and determined to win.
It seems to me that being a 'technical' player is relative thing. For example, a super-skillful 14 year old has no chance against an adult non-technical player.
So, in general, anything that serves to protect the goal line tends to be less technical whereas the opposite applies in order to score against the opposition.
I agree although I think it might be a little more accurate to say that players who have to fight for 50/50 balls are less technical vs players who distribute and move the ball. There are some strikers who aren't technical at all, they just fight for the ball and work really hard.
