Gilchrist average 35 in ODI's. Was he really the holy grail?
If a keeper averages 35 in Tests he's doing well, if a batsman averages 35 in ODIs he's considered to be a good ODI batsman.
Maybe you're lost with numbers, this is the WICKET-KEEPER and it is ODIs not Tests. Or perhaps because these days some players average 40 and 50 in ODIs you're taking that as a benchmark, well Sehwag only averages 35 in ODIs, Tendulkar averages 44, Smith 38, Kallis 45, Jayawardene 33, Sangakarra 38, Clarke 45, Pietersen 41 and Watson 41. That's a sample of the kind of average some good batsmen achieve, there are others who average 50 but in the shorter form of the game that is still exceptional and largely down to much flatter tracks and rule changes.
And of course Gilchrist was notorious for big hitting, with a good ODI average for a keeper and opening he was bound to be a template. It isn't my "holy grail", I'd rather our keeper was like Gilchrist than not, but I wouldn't try and make every keeper open and hope he does what Gilchrist does which has been what England have done in the past. It's the whole pinch-hitting theory, while Sangakkara averages higher than Gilchrist, their respective SRs are around 75 compared to nearly 97. So let's have a little look at the averages of those listed with SRs
Sehwag : ave 35, SR 104
Gilchrist : ave 35, SR 97
Watson : ave 41, SR 88
Pietersen : ave 41, SR 87
Tendulkar : ave 44, SR 86
Smith : ave 38, SR 81
Clarke : ave 45, SR 78
Jayawardene : ave 33, SR 78
Sangakarra : ave 38, SR 75
Kallis : ave 45, SR 73
The most any of that sample could average with an SR above 80 was 44. The two with the highests SRs averaged well under 40, not really a surprise and given Gilchrist might just have spent 50 overs keeping, I'd say to knock an average of 35 is naive.
And to pick out some who average 50, or one on the brink :
Amla : ave 59.96, SR 91.73
Dhoni : ave 52.29, SR 88
Kholi : ave 49.99, SR 86
Oh and big hitter keeper McCullum averages a tad over 30. Amla seems to be the ODI batsman uber alles, phenomenal average and SR. I couldn't see any other batsmen listed as current with 50+ averages, I would reckon on 45 being a top average these days and 40+ would have been through most of Gilchrist's career. Either way, 35 from your keeper you would take and without hesitation if at an SR over 90. Most sides would want their keeper to score at a quick rate down the order, anything over 30 would do.
England "current" keepers (ODIs)
Kieswetter 30.67
Davies 30.50
Prior 24.19
Mustard 23.30
Read 17.65
Foster 13.67
Ambrose 2.50
Davies actually averages 34.14 opening and has an SR of 105.63, has only played Australia and Pakistan, so why he only appears as a blip on the radar I do not know. Funnily enough Kieswetter who was in the side to pinch-hit has averaged 33.83 at six compared to just 29.96 opening, although that is skewed by 3/9 being not out batting six, but then he didn't get to finish his 21no (224/4), face a ball in his 0no (252/4) or finish his 38no (288/6 after 50), so strictly speaking it's only two not outs that made any difference and in both he probably would have made a few more runs with more time to bat
