That's to some extent what I thought too. But then we had last year where many stages were marred by the lack of breakaways. The explanation was that the teams were not interested in exposure as in the old days - they wanted results.
The problem is that the teams
are interested in the exposure, but the means of it is different.
Back in the day, you got those breakaways because the team's sponsors were interested in the TV time as their exposure, and by animating the race and making those attacks, the team curried favour with the race organisers that would help them get future invites as a thank you for providing spectacle in the race.
Nowadays, almost all of the invites are guaranteed as long as a team scores a fixed number of points, and mediocre finishing placements are therefore valued far higher to teams than television hours. The sponsors will say that they want the visibility, but the crucial thing is that racing boring and accumulating placements
does give you the visibility:
by guaranteeing your presence in the most important races.
For obvious top teams like UAE, Visma, Red Bull, Soudal etc. that's not really an issue, but the fact that accumulating those placements guarantees the invites rather than being at the mercy of the organisers (when the organisers only have two teams to invite at their discretion rather than the six or so of a couple of decades ago) means that we're seeing the kinds of teams that used to provide that TV time action - the equivalents of today's Cofidis, Arkéa and IPT - placing greater value in protecting placements and sprinting out minor places because it reduces TV time today for a guarantor of potential TV time tomorrow. Meaning that we're often seeing those teams doing things like bringing in sprinters who they know full well are unlikely to even come close to winning a stage, but can at least consistently come 7th in the flat stages, because while it's less glamorous and offers little in the short-term, it's more valuable long-term than a few days in polka dots or combativity prizes on any day where the péloton actually wants to chase the break.
