Tim Horan (67)
Reckon Jock would have way more experience than Wright at fullback. He's also a calm head at the back which is what you really want. Not a tempestuous one.
Both have played pretty much the same number of Super Rugby games, having debuted the same year, but obviously Jock has a heap more at fullback (a number with Petaia on the wing).
Wright has more test caps obviously but the same number as test starts at fullback.
Jock is also a couple of years older too.
Rennie is just trying to justify a gut decision.
