The reason I didn't put Murali in Level 1 is because I don't think as a whole cricketer he was as good as McGrath or Gilchrist. Gilchrist I rate in the pantheon of great cricketers. He practically revolutionised his position and is one of the few dead certs in an all-time great XI. McGrath I rate simply because I don't think any fast bowler will have his record, or play long enough to have it - or have a record as good as his if they played as long - and is one of the bright spots in what hasn't been the best era for fast bowling. I think I rate his intangibles also, in that it's largely due to characters like his and Warne that we were #1 for so long. I think Ponting is well-placed and is only easily outshined by the top 3 in my list of my players. His all-time great batting, his all-time great fielding and his record breaking captaincy puts him on a higher plane than Murali IMO, obviously. I think if there wasn't a Warne who did what he did, at least to the same degree, then he'd be up there. But already having Warne, with all his other qualities I guess makes me rate him less. It would be like having an equivalent to Gilchrist.
WRT to Chappell, I just think he played too little cricket. Gavaskar suffers worse because his record is not very good post 1980.
I think the neutral choice, in terms of what most people would agree to being the greatest cricketer post 1980, would be Imran. His captaincy, bowling, even batting towards the end...and in general how he made Pakistan a force is hard to beat. The only reason I have Warne above him is because I saw much more of him (his whole career practically) and am convinced he is the greatest match-winner of all-time - however I may seem to define that.
I didn't really think about it a lot, I'm sure there are players I could swap around if I thought about it more.
