At their very best, Remco is the slightly better TT'er. So he should be minimally better on the flat in perfect conditions. Perfect conditions rarely exists. And pogacar the strongest rider atm (and prob. will be most of the time). Fatique, form of the day obviously matters.
That said Remco can be proud of today's race. Clear 2nd best. Without Pogacar he wins his first Lombardia today. Obviously Pogacar raced. So that point is moot. Still Remco did well, Especially after how bad it looked last week.
No doubt he would rather have won, but best Lombardia result so far. Can definitely be happy with that, and maybe built on it.
Honestly, remco looked strong today. However there exists this one man who can simply do things no one else seems to have answers for.
