The post wasn't about winning though, it was about running away with it.
If the race comes down to a select bunch of 5-10-15, and Thomas wins from that, either in the sprint or with a tactical move, or if conservative or neutralising racing behind means that many major contenders are in the wrong move and Thomas is in the right one, then there may be some who would keep this thread alive with their talk, but it wouldn't be the same as if he put the hammer down with 45km to go, dropped Cancellara and Sagan and soloed in by over a minute.
Put simply, if he wins in a 'normal' fashion for a peripheral contender, by being the smartest or by being the strongest on the day in a close-run thing, then there shouldn't be too much trouble. If he wins by putting the hammer down and riding everybody into the dust, then there will.
But hey, he's got to actually do the ride first, and to be honest I see Stannard as the bigger threat from Sky at the moment. That junior Roubaix win for Thomas was 9 years ago now, and he's had a patchy rate of success in the Classics to date; Stannard is a workhorse and I can readily believe that he could win the race if he follows or makes the right move.
