That's a very agreeable definition and McGrath didn't fall into that bracket, though tbf I think the post you originally responded was describing him as fast in the commonly used sense of 'not a spinner or a genuine medium pacer'.
Yeah, the actual skill of a bowler seems to be overlooked so often (not so much by CW course) when it is of course somewhat important - see Saj Mahmood.
Similar kind of thing with spinners, a guy at work was basically saying that Moeen was struggling (against Sri Lanka, I think) because he was some kind of right-arm Ashley Giles, when the problem was moreso that he was bowling a lot of balls for which the term 'pie' would be somewhat flattering.
I mean, even Herath doesn't generally spin the ball miles and he's indisputably the best bowler in the world right now
