Ice I also think Djok might turn up with no match play and win the whole thing.
Re- Casper, I think it's the fact he's had a pretty rotten few months since RG, and doesn't seem to have any form indoors (didn't play well really at the Laver Cup). I don't know if it's lingering illness or not. Bit like Rafa, I feel like it's not really his time of year.
I know he's scheduled for Metz- another first round loss might just seal his fate (he might not qualify anyway, if ADM /Grigor do well this week).
