Nothing, but suggesting that you can leave Southee out because Boult "has been exceptional" ignores the reality that Boult hasn't been bowling that well as of late, and his exceptional ODI stuff all came back before he got injured.What do Boult's hypothetical post-injury ODI performances have to do with Southee's actual post 7-fer numbers I posted above? They're utterly diabolical in anyone's language.
I was responding to Albi's point that Henry/Boult being so good means you can drop Southee out of the first XI. If that first point doesn't hold, it casts doubt on his second.
There's also a 'form is temporary, class is permanent' argument to be had there, I suppose.
