Personally, in Twenty20, I like to have 1, maybe 2 big slogger openers, 1 or 2 grafters, who guys who nudge it at 3 and sometimes 4, and sloggers at 5, 6 and sometimes 7. Then the tail.Generally, I think the first three batsman in the side are openers. Which means you have to be able to face the new ball.Also no.3 and no.4 are the powerhouse of the team.Which means you also have to score many runs and anchor the entire innings.
Hey 99.....what are they are the bottom of your message ..."madden stats"?In a 20 over game, you should try and stay at a run a ball, try and do this until you're in the last 6 overs and from there attack. Playing like that will normally get you a score of 60-70 which is a good score.
If however you are 8/9 down you should wait until the last two overs to attack. Since you do not want to get out yourself and leave the tailenders to slog out.
If you are defensive, you shouldn't be batting at 3 unless you are promoted to come in after the first ball at 1/0. In a Twenty20 match, there really isn't time for a defensive batsmen so high up the order, and if the openers make 40-70 there wouldn't be much time to play yourself in.IMO. The role of number 3 depends on how the openers went.If the openers got out early you try to steady the ship if they make 40-70 you could build your inning's slowly or how ever you bat (Def,Mod or Agr).I know i have batted at 3 and 4 before in my grade.
