ok im pretty much off on hols so i type thi squickly and without thinking to much so flame away

only ideas if you want to expand even further the live commentary
For a number of reasons I think it would be very usefull to know where the ball is.
I would say 6 areas.
home
penalty area,6yard box,box to half way line,
away
line to box, box to penalty area.
this allows alot of scope in the commentry.
we currently dont have throw ins corners or goal kicks. but we can synthersize these events just by knowing one more thing,, where is the ball.
for eg if the ball has changed possession rather than it allways being as a result of a tackle there is no reason we couldnt call it a throw in?
eg 2 the homeT has the ball,its at their penalty area and we get a change possesion. we could synthesize a corner out of this?
we have the ball and we are in our defence, knowing this allows us to say ourteam is trying to clear the ball.
as you can see this leads us to all sorts of commentary we can add lots more.
another bit of info!! time spent in areas
Having a percentage of time spent in each area also gives us a whole heap of info to comment on. the game is stalling in the midfiled could be said if the mid areas have the highest percentage.we can also deduce things like.
team A have had the most possesion, the ball has been in the team Bs hlaf most of the time.. Team A just cant crack the .defencive wall team b have built.or team a just cant get the ball out of there half, team b's midfiled is too strong, etc etc.
