We've had this conversation on here before, and there is a reason why the normal "convention" is to quote games started and goals scored as one of the main criteria.
There's merit in both, obviously, but not all players are the same. Plenty require time and minutes to get themselves into a game. Strikers don't want to come on as a sub for lots of obvious reasons, and that's one of them.
Taking your "minutes played" to an absurd length, would a player be more fairly rated, or happier, with two full games at 90 minutes to show their quality, or 18 games in which they only come on for the last 10 minutes?
They may only get one chance per appearance. Or none. And who scores from every chance?
Starting games is also a psychological boost. It shows you have the trust of the manager and your team-mates. They are set up to play with you. A perma-sub may often simply try too hard to impress, knowing they only have a very small window.
Benteke scored 9 Premiership goals in only 14 starts. That's impressive. If he'd started every game at that rate of scoring he would have scored 24.
