McCullum has taken the shortest form of the game by storm, notching a staggering world record score of 158 not out from 73 balls in the IPL.
"I played with the likes of Sourav Ganguly and Ricky Ponting in the IPL and you can't help but develop when you train alongside those guys," he said.
"The England guys would benefit for that reason. Financial gains are part of it but the best part is the experience," The Sun quoted him, as saying.
"We're not jealous of the Stanford games. The ball is in the player"s court - if you perform you can earn lucrative contracts from cricket," he added.
The big-hitting batsman is convinced his time in India has helped him to develop his game. And he reckons England's finest should now do the same.
And with reported earnings of 350,000 pounds from his Kolkata Knightriders deal, rather than the winner-takes-all element of the Stanford games, it is easy to see why.
"Scores like the one I got for Kolkata don't come around everyday but I know I have more of the same in me. I'd be disappointed if people didn't see us as joint favourites. Ok, England has the momentum but this is where we are most comfortable," he said.
"We're quietly confident and have a great chance to turn around our tour," McCullum added.
