In each match, Anderson has bowled three overs in the powerplay, going against the modern tactics of changing it up.
He has backed his skills against batters looking to attack and take advantage of fielding restrictions in the first six overs.
And Jennings acknowledges that the England great’s skillset is still relevant, with Anderson’s economy rate inside the top 10 in the competition so far.
“He’s somehow moved with the times of T20 cricket without playing a game,” said Jennings.
“That shows the level of care he’s taken in his own cricket, his own preparation.
“He’s bowling nice and quick, he’s controlling areas, watching batters, following them, going wider when it’s needed.
“When he does mis-execute, he doesn’t seem rattled and he’s straight back to what he needs to execute next ball.”
