I think the monument comparison is very flawed.
Pogacar gobbles up a lot of Lombardias, a race that should automatically disqualify because it is held in October where 80% of the field is already on holiday mode eating cookies and drinking beer the week beforehand. The sole reason why he keeps winning it is because he lives like a boring monk and would probably also in form when you wake him up in mid December. Hard to give him credit for that.
The only time it was held in August in 2020 it had immidiately a very respectable winner in Fuglsang.
LBL is tricky. On one hand it has some incredible respectable winners such as Frank Vandenbroucke, Vino, Andy Schleck or Fuglsang. On the other hand, any race that can be won 4 freaking times by Valverde should immidiately be discarded as a relevant race. So tough call.
That basically leaves MSR, Roubaix and Flanders. MSR would be a great comparison but MVDP has disqualified the race from being a measuring stick since he decided to babysit for Philipsen, a disgrace that leaves me no choice but to only look at PR and Flanders. Where it currently is at 2-2. Tough one.
