Grondal should do an ok job - he was struggling to find a setup apparently.
Should get to an ok middle order level.
Obviously replacing the weekly guest scores of Brady Kurtz with Grondal's will cause a bit of a reduction, but in fairness, Kurtz only scored 6 from 5 and then 9 from 5 in his last 2 guest appearances!!
But given the choice was r/r for Allen, or signing someone like Grondal, it was a choice that had to be made.
R/r for most of the season is too much of a strain.
As far as the other major error as pointed out by Lukas (Grondal was the first), I would say that Konopka needs to be given the benefit of the doubt at the moment.
OK he only "earned" one of his points yesterday, but he might just need better equipment.
There have been other slow developers in the past.
