A2-A9 is a bit different
For exmpl.: A2-A5 can bee god in MP due to draw potentioal so EV+, But A6-A9 is bad in MP, as you are most likely be dominated post flop,
even if you are posstion, it can be hard to get of a paird A, but you will be loosing to much if you will be going to SD with it too often + in 3+ way pots drow
hands like 79o are getting too good of a price to float for a few streets.
