Would you consider a decreasing amount of games he’s fit for playing a sign of performance drop or are you saying as long as he can be world class and play one game a season we should keep?
It’s not a question of ability - it never was - it’s a question of whether his body is up to it.
I’ve argued that his fitness isn’t a problem in past, but the evidence suggests it’s becoming increasingly so - last year he missed a fair chunk… this years is looking equally problematic.
It’s definitely something that should be considered.
