It's one of these self fulfillingn prophecy stages. If everyone believes a sprint is inevitable, they may act like it.Axelgaard thinks it will only be a reduced sprint very much like yesterday and basically rules all other scenarious out. I think that seems rather ill-advised. I'm not saying it can't happen but it certainly isn't an odds-on scenario for me.
But realistically, for 90% of the teams the best chance to get something from the day is from a breakaway.
