International Debutant
McGrath bowled on flatter pitches but arguably in an era when defensive technique was also weaker. And India is an exception; pitches were definitely flatter in the 80's. Marshall's success in India suggests he would have no problem coping with flat pitches in the last decade. McGrath does deserve credit for longevity but ultimately there is very little to choose between the two. I would probably pick Marshall because he was a bit more useful as a batsman and perhaps a touch more menacing at his peak.
