There's also something called "first mover advantage", which kind of contradicts your "football effect". There have been a ton of altcoins created, none of which have crushed Bitcoin. Bitcoin is still holding on to the football quite handily.
Perhaps Bitcoin will fail at some point in the distant future, but for the time being it is absolutely the most influential cryptocurrency, this can easily be seen by all altcoins' value being pegged to their BTC conversion rate.
