If Sunrisers Hyderabad coach Trevor Bayliss is not selecting Williamson for team balance reasons rather than elbow flexion issues, he will justbe the latest coach with a bone in his brain when it comes to assessing Williamson's worth as a T20 player.
The Black Caps' skipper has missed the first two matches of Sunrisers Hyderabad's 2021 IPL campaign because he lacks "match fitness", after sitting out the last month of New Zealand's golden summer due to elbow soreness.
You can take that explanation as gospel or with a grain of salt – given that IPL contracts are paid out pro rata based on availability, there will be some semantic gymnastics around the differences between the terms "not match fit" and "unavailable" – but it doesn't alter the fact that Williamson is chronically underappreciated and underpaid in the IPL.
Williamson's class and unparalleled ability to read match situations should see him as the first player on any team sheet, with a (c) following his name.
There are historic reasons to be sceptical about Bayliss' explanation for Williamson's absence. The former England coach works under the Sunrisers' director of cricket, fellow Australian Tom Moody, who has history for leaving Williamson out of the XI when he was head coach, even when it was obvious they were a better team with him in the side.
The serenity Williamson brings to proceedings was sorely missing this week when the cameras caught David Warner blowing up in the dugout as his team butchered a seemingly simple run chase against Royal Challengers Bangalore.
"He was a little animated because we weren't playing very good cricket and we lost," Bayliss said of his captain. "I think the umpires got it right."
This is not a dig at Warner – the best performer in Sunrisers' history and one of the best T20 batsmen of all-time – for the sport of it. We won't even mention a certain ethical incident that should have disqualified him from ever leading a Sunday pub side again, but there has not been a world imagined where the feisty southpaw would be a better captain than Williamson.
People point to Williamson's unspectacular 125 strike rate as an impediment to selection but that's a one-dimensional way of looking at T20 batting. Williamson plays the innings required of him to win games. If it means feeding the strike to big hitters he'll do it. If it means taking the sting out of the opposition's most dangerous bowler, he'll do it. If it means trying to clear the ropes he'll do that too, though it will never be the strongest part of his game.
He's a quality player who improves all those around him… so it is imperative that Bayliss and Moody continue to leave Williamson out of the XI so he can instead spend his time in the nets practising with red balls followed by icing his elbow.
The Sunrisers finish their round-robin campaign on May 21. It should be every New Zealanders fervent hope that they finish outside the top four and Williamson will have plenty of time to connect with the national squad in England ahead of the first test against the hosts at Lord's starting June 2.
It is your national duty to wish ill upon the Mumbai Indians (Trent Boult), Royal Challengers (Kyle Jamieson) and Sunrisers, but especially the latter.
While it's a shoehorned tour and while IPL availability is pivotal for the future health of New Zealand cricket, there's still something a bit smelly about the prospect of playing a test at Lord's without your captain and best player.
So Tom, Trev and Davey, this is a heartfelt request on behalf of New Zealand fans: do not pick Williamson, he's not match fit.
