It has left the likes of opener Fakhar Zaman and fellow top-order batter Saim Ayub to fill the void and Hesson believes his batters are still evolving and learning how to complement each other when at the crease.
“It’s very much a developing batting line up,” Hesson said on Thursday.
“And there’s a number of players who, on their day, can win you the game, but they don’t have as many good days as you’d like at the moment.
“I think that’s very fair. The thing for us, though, is we’re more interested in the sum of the parts as a batting group.
“Because there are times where 150 is good enough, there are times where 190 might not be.
“So you’ve got to, as a batting unit, decide what’s required to win the game and see if we can get above that.”
