Traditionally, the TT has been 4 days before the RR, and it's been too close to really peak for both, especially if the TT had been very long.
Now it should be more doable, but with the difficulty of the road race, Pogacar may have done less work on the FTP for the ITT.
If Pogacar does one of his best TTs, it's not interesting, because he wins it easily
Evenepoel generally has larger margin in TTs, even at 70% form (when he flops in the mountains) he still smokes them. Pog can flop in TTs when not in top form but this route compensates for their normal TT dynamics.
