Oram's average hovered around 40 for almost his entire career up until his last couple of test, when Murali took a big steaming dump on it. He'd make almost any New Zealand team in history as a batsman alone.
Will have to check when I get home, but I recall Hadlee saying in "Changing Pace" that the decision to turn Oram into an all rounder rather than focus on his batting was slightly controversial in some quarters.
I remember reading a Palmerston North Boys 1995 year book (for some reason it was in our school library) and Oram was absolutely dominant with his batting and his goal keeping. I remember when he was in that successful Under 19 team that won in England in 1996 and captained by McMillan. He batted number 5.
He quickly shone for CD, with big hitting efforts in Cricket Max and at first class level.
I don't recall him doing much if any bowling until later on, and IIRC was always about 130 kph, although his height and consistency made him very awkward. In the 2004 test series against England I recall the commentators saying that Flintoff's bowling was about 10 kph faster, although Oram seemed the better batsman.
In hindsight I wonder if he had just focussed on his batting his career might have flourished more and been more sustainable given how blighted he was by injuries. Although he would have had to push out Styris, Astle or McMillan for a middle order spot.
My favourite memories of him are batting with Cairns against South Africa (never saw that 2004 Australia test), the massive hit onto the roof of Lancaster Park in 2005 Hadlee/Chappell (won the game in great partnership with McCullum) and his incredible hitting in the 2006/2007 Tri Series with England and Australia. Also, he's on the honours board at Lords which is pretty cool.
