Twenty20 cricket innovations

Cricinfo - Four stumps, and first-ball free hits

Interesting article that advocates
1. Four stumps behind the batsmen
2. No leg byes
3. Extra over for bowlers who take a wicket

by way of encouraging bowlers in this batsmen-centric format.

I say, we have had many such innovations in street cricket for a long time.

1. No runs behind the stumps
2. One pitch catch
3. Batsman is out if the ball lands in a certain area
4. Bowling XI different from Batting XI

and one for the batsmen

Last man gaaji (continue playing even if the rest of your teammates are all out)
