Surely there needs to be a balance!
I remember in the late 70's/early 80's, the likes of Ovett & Coe might have a go at a WR 2 or 3 times a year, but most of the races (albeit on a more limited circuit) in a season were proper tactical affairs. Sometimes this would end up in quite predictable "home straight kicks" in slow times, but there was some variety in the sport and it was more exciting.
Fast forward 20 years and it seems like every 800, 1500 and 5k run in Europe in the big meets have not just one, but sometimes a whole host of pace makers; who have become extremely good in giving just the right pace. It's as if it's become an essential component. What makes it ridiculous is that half the time none of the other athletes are wanting to go with the pace, so the whole exercise is rendered pointless!
Another point is that perhaps this call for "banning" pace makers originates from a desire to stem the tide of the overwhelming dominance of African athletes in middle and distance events. Would they want to see the practise curtailed? I doubt it, as they know they have far more chance in winning if the pace is fast from the outset. Getting rid of "rabbits" will result in slower and more tactical affairs, which will definitely level the playing field for European & American athletes, resulting in more wins for them and the possibility of more youngsters from these parts joining in and believing they too could succeed in such a pursuit.
As much as I believe "banning" pacemaking would lead to a resurgence in western athletes' success, I do not think it would be the best thing for the sport and maybe almost impossible to enforce.
Apart from being about competition, isn't the core of athletics, how the individual should be encouraged to explore the limits of their own talent and ability? This would not be possible if pacemaking were banned, as athletes would be encouraged to hold back and run below their full potential.
Moreover, if you have 5 or 6 Kenyan sub 27:10 men in a race, and they all go to the front and run as a team (perhaps say in an Olympic final), who and how does one discern that they are pacing each other, when the legitimate claim can be made that this is how he/they run in order to win the race!?
I think the best solution is a "middle path" where promoters are encouraged not to use pace makers so frequently, and have perhaps a set number of races spread out over the year where athletes and promoters alike know in advance that "rabbits" will be present. One year let Oslo, Zurich and Rome have them, the next Stockholm, Brussels and Rieti.
