Why not back a Granada win?

Because at home, they haven't shown anything convincing lately and are coming off a summer of departures. Covering the draw is more prudent than betting on their victory alone.

Isn't Mallorca better equipped?

On paper, they are in slightly better form, but their squad value has melted away this summer, they're traveling without three players, and they rarely win away from home. Their advantage is slimmer than it appears.

What if Mallorca wins anyway?

That's the assumed risk: they are on three wins from their last six matches . But the double chance only fails on a Balearic win; a draw is enough to validate it.
