Well I dont want to be sad here again, but I think that manager should have to do something first to have the right to vote. Like acceptance with that, then it would be at disposal (normally that would be done autmaticly). It is just because lot of managers just will not vote, because it is too much work. Just look at NT elections and real volume of users in that country.
The participation will not be 100 percent.
You are talking about published votes. I think that there has to be that - if anyone voted for your player, it has to be mentioned on players page (if you click on him) even for not involved users. This will create propagation of this feature and in advance propagation of your succesfull player.
Aditionally I think that there has to be during voting any list of players (sorted by wage or results, I dont know), with his name and team where he belongs, so you can look at them at one page and have life easier during voting.
