The Gers have got off to a flying start under Mark Warburton this season.
McGraw was part of the Greenock Morton side that went on a 23-game win streak to clinch the old Second Division title in 1964, and after casting his eye over the Gers, the former striker - who bagged 117 goals in 136 games for The Ton between 1961 and 1966 - thinks they can do one better.
“I was at the Rangers game against Raith Rovers last Saturday when they made it nine wins in a row in all competitions and I feel they could win every league game,” he told the Daily Record.
“Mark Warburton has put a good team together… I have seen a few Rangers games this season and they are capable of winning them all and beating our record.”
McGraw bagged an impressive tally of 58 goals as Morton wrapped up the title in February – the earliest in Scottish football history – and suggested a current Rangers star could match his record, adding:
“People ask me if it can be beaten but I really don’t know. It is different now but who knows? It could be passed by a Rangers player this season the way they’ve started.”
The high praise from the Morton legend comes hot on the heels of Ray McKinnon's assertion that Mark Warburton’s men can maintain their 100% record all season.
It’s a testament of the start made by the Gers and while the unpredictable nature of football would suggest there will be hiccoughs along the way, the men from Ibrox are clearly head and shoulders above their Championship rivals.
