What does -- mean when creating pick screen

I went to enter a pick on the streak survivor page & the pick I wanted to use was off the board.

I notice the pick I wanted to use had a -- under the column on the pick I wanted to use.

Does the -- indicate the play is off the board because too many people are on that play?

If yes, is there a certain % of people have to be on that play & what is the %?

Thanks for the information.

 -- means it is unavailable due to either the odds being too high or consensus rules (too many people picking one side). The percentage required seems to fluctuate.

find the consensus rules page its all explained there

i think its anything higher then -130 for odds to take the game off the board
