Sorry but no. There is a big difference between fresh TT ability, and rouleur ability after 250k of racing. I've already used the same example between Van der Poel's solo wins and those of Evenepoel, but the same goes for Pogacar (but less extreme than Van der Poel). Pogacar went solo 18k to the finish, basically on the last big climb. His timegap at the finish to Van der Poel? 17 seconds. Except for the initial acceleration, not that much was added on the flat towards the line. When Evenepoel went solo in Liège, he had 18 seconds to a chasing group (which used to be the peloton) on the top of the final climb. In the next 13km of flat he expanded his gap to 48s, while even starting celebrations 3k from the finish. You could argue that unlike Van der Poel in Ronde, the chasers were looking at each other, except that Vlasov (who had not worked in the chase before RaF because Bahrein were still there) also got a gap, but was taken back by these same chasers right before the line. If they were truly not organized or committed, he as well would have been able to stay clear. So at the least, they had the speed to keep another solo rider in check.
At the WCC, Evenepoel expanded his lead over a group of chasers who were 100% committed to racing for a medal, steadily to 2 minutes. This group was caught by the peloton in the final kms, while Evenepoel did not lose one second of his lead to the peloton.
Pogacar seems to have a (much) easier time getting a gap and seems to be able to expend it slightly initially and then hold it. His gap in Strade last year, i remembered it as an insane solo where he obliterated the field... 38 seconds to Valverde. Fresh TT ability has little to do with it. Show me the 250+k races that Ganna or Tony Martin dominated, they don't exist.
