Playing as a prop, depends on you as the person playing in that position. It doesn't help you try and focus on becoming a ball carrier if you're not good in that area, in that you can't make explosive runs, or have a burst of speed or is tough to bring down.
Scrummaging is the most important part, but also lifting in the lineouts, tackling, and work at the breakdowns. We are currently seeing that props with good hands who can make proper passes and offloads, play a bigger role in games, while supporting the more elusive runners. securing the ball at the ruck, or trying to steal it like Steven Kitshoff and Trevor Nyakane, brings more value to the team, than a guy who wants the ball in his hands, but can only make 2 or 3 meters with a run over the advantage line.
There is nothing wrong with a prop doing just the basics, as long as he does it well. If you can't scrum, you'll give away penalties, and put your team on the backfoot the whole time. If you can't lift at the lineout, your locks can't win the ball. If you can't protect or win the ball at the ruck, the opposition will keep on attacking.
The props are not there to be flashy players, they do the grunt work and get little praise.
Look at the 2019 World Cup final, heaps of praise to Duane Vermeulen, Handre Pollard, Mapimpi and Kolbe. But everyone forgets it was the props that decimated the english scrum and allowed the Springboks to win penalties and build scoreboard pressure.
