I agree with Mike here.
Warning RANT ahead.
I see too many F3's playing with their foot stuck smack in the middle of the base and too many runners trying to plunk their foot down in exactly the same spot. That's why there's all the clamor for two first bases. If coaches would teach their F3's to use the inside edge of the base and their BR to step on the outside half of the base then a single base would be perfectly adequate (is that an oxymoron??) for 90% of the plays at 1st.
If people are so worried about collisions at 1st then they should just move the orange base about 4 feet to the right or teach their players the proper way to field and run.
