From the Champion Hurdle thread:
The stable’s Zarkandar won the Betfair off 151 on his 5yo seasonal debut and went up to 163 for following up with a solid run in the Champion Hurdle, eventually going up to 168 for winning the Elite off that mark the following season. If Cliffs Of Dover is anywhere near that ball park the current 33/1 will look like Christmas come ten months early.
But he has to get there.
He might be another John Constable (NR in the Betfair off 139, well beaten off the same mark in the County and eventually came good at the end of last season and is now entered for the Champion off 156) or Blue Bajan (well beaten off 128, went up to 146 for winning the Swinton off a higher mark and eventually was rated - rightly or wrongly - 160).
