Does anyone know what is the deepest possible league in Yahoo? Thought it would be an interesting idea to put one together next year so would appreciate your thoughts/experiences of such leagues.

Number of teams
I play in a 20 teamer, is this the maximum?

Number of categories
Are there hits, blocked shots etc? However, I probably wouldn't use them all as there would be major duplication (e.g. G/A, P, PPG, PPA, PPP etc).

Number of starting slots per position?
The most I've experienced is 4, can you go higher? And if so, is it restricted depending on the total roster size?

Use of multiple positions
Using C,L,R,F,U,D etc. Same question as number of starting slots, is it restricted by roster size?

Total roster size
Given all the above, is there a maximum?

However, I do understand that increasing everything may not work given the type of league (e.g. situation with a H2H league, 20 teams, limited goalie slots, minimum weekly games, and a high ratio of goalie categories, etc).

If anything, it would be good to start a discussion on what has and hasn't worked for you in the past, and tips for next year.

Thanks in advance, and Happy Holidays!
