Champion Data’s Glenn Luff has revealed the depth of Adelaide’s injury crisis.

Based on the AFL’s rating points, the Crows have three of the top four highest rated players sidelined with injury, severely depleting the quality of Don Pyke's best 22.

“We’ve got Adelaide losing the most to their best 22, then you’ve got Geelong, the Western Bulldogs and Collingwood,” Luff told SEN Afternoons.

“But if you take it to another level and take into account the quality of the player by using the AFL rating points, Adelaide have clearly lost the most – there is an excuse for what’s going on.

“They’ll be playing catch up from a long way back.

“Of the players that have lost the most through injury, Brad Crouch is number one in the competition, then it's Rory Sloane, Toby Greene and then Brodie Smith.

“You have to include Smith because he’s a part of their best 22.

“Three of the top four are Adelaide players so there’s a genuine excuse.”
