The other software that I used to use was Football playbook by Jes-Soft
I ended up buying the pro version which was pretty reasonable.
Its actually a pretty good piece of software It also let you generate good practice plans on the fly, and animate plays so when your doing film sessions you can show how plays work.
The problem with it to me was that the field area felt too small.
But I also liked using Hudl more because you can link to video

I think I used it for about 8 years before I jumped on Hudl.
