Shame because I feel the points jersey belongs to a sprinter, or at least someone outside the top 10 of GC.
This is a common misconception; perhaps because the Tour de France skews the available points towards flat stages in order to give the sprinters more chance to win. Most races go with the same system as the Giro and Vuelta, that is, 25 for the winner, 20 for second, 16 for third, 14 for fourth, 12 for fifth, then 10 down to 1 for sixth-fifteenth, or a similar one. The points jersey is designed to reward consistency - in fact in Spain it is often called the maillot de la regularidad
. The winner of the points jersey is often either a sprinter with consistent good results, or a GC candidate. Danilo di Luca won it last year but the year before that Daniele Bennati took it, which allows for a different aspect to the competition. It can create some interesting battles, as lesser GC men who can be 'up there' in mountain stages can then get in the mix for the sprints in flat and intermediate stages in order to compete for the green jersey - Kim Kirchen in the 2008 Tour springs to mind in particular here, but Damiano Cunego has also been known to behave thus.
