My thought process in selecting an ATG One Day Team (if anyone cares!)
I reckon Tendulkar is basically the best all-round one-day batsman ever, so he is my first selected in my all-time XI. He is the rock that opens and can bat sensibly but accelerate heavily as necessary
Next consideration is who he will open with, and obviously Gilchrist is considered here. Ideally my other opener will be a left hander, but I consider Greenidge strongly. However, I take Gilchrist as an opener/keeper, as I think he can be incredibly destructive, perhaps more than anyone other than Viv.
Viv goes at three, no questions. Could tear a match apart in a matter of overs. Great fieldsman, which is important.
Number four and five could be filled by plenty of excellent batsmen. I will consider Dhoni seriously in addition to Gilchrist at some point, but at the moment I take Ponting and Lara. Middle order L/R combo, both capable of being brutally destructive against high quality attacks. Both fielders of the highest calibre.
I take AB DeVilliers at 6 simply because I love him. Extraordinary fielder and high quality bat. Having Richards, Ponting, Lara and AB in my team as fieldsmen is an important part of my selection thoughts. Symonds considered strongly and unlucky to miss out. I remember the Australian teams that had Ponting, Clarke, Hogg and Symonds, and the WIs who had Richards, Lloyd, Logie and Harper in the field, and how much pressure that placed on the batting team by drying singles up.
I don't bother with a "finisher". I'd much rather Lara in my team than Bevan.
I take two all-rounders at 7 and 8, both of who are also elite bowlers in Imran and Kapil. This gives my team flexibility. Kapil was a great ODI batsman, and I think he is a better option than Klusener as both a batsman and bowler. Wasim is one I'd like to include, but just misses out.
Warne I take because of his competitiveness, but would be equally happy with Murali.
Garner and McGrath as quicks. Opposition could quite possibly be three for nothing after the first ten overs from those two miserly pricks. I rate economical bowling very highly in ODIs.
