IPL and Economics

When everyone is talking IPL as batsman's game, I think the classic principle of economics need not be overlooked. I am of course talking of demand-supply principle.
When an item is over supplied, it loses its sheen a bit. In terms of IPL, the batsmen have been having a good time, however the teams which have managed to have lowest bowling averages, in my opinion, are the strongest.
Even a run rate of 10 doesn’t look beyond reach, but if you have 2 bowlers who can give you 1n over each of 5 or so towards the fag end of the game, it changes the complexion of the game a LOT.
The recently concluded game been DC & DD is prime example. 2 decent overs by Symonds & Vaas took DC were enough to take DC to a comfortable win.
