What I'm saying is that SMB didn't need to win a Bumper to becoming a long-time, top-grade horse. You seem to be implying that winning a Bumper or two means there's another genius chaser in the making, Treetangle, but Bumpers equate to diddly-squat. They're intended to get some wannabe chasers acquainted with courses, and aren't an end in themselves. With Bumpers you're talking about potential, full stop. Let's see how CUE CARD does once he's tackling obstacles, and shows he isn't a one-trick wonder. The road to chasing stardom is littered with bright Bumper horses who showed all the potential in the world - and failed when push came to shove.
But your beef was about Joe Tizz riding, not the qualities of SMB or any other brilliant chaser, to which the riposte was that he'd ridden something none too shabby on a few occasions. But I guess it doesn't really matter what anyone says to you, because you seem to have a mind cast in concrete when anyone offers up an alternative point of view. C'est la vie - I don't actually care enough to continue.
