I dont think Sprinter Sacre is worthy of this adulation yet. Cue Card was too close and in with too much of a chance coming to the last in last years Arkle for him to be getting quite this much respect. I think he is good, and Im not sure if Sanctuaire is the one to beat him, but I'm not convinced he is as bombproof as Master Minded or Moscow Flyer yet. (they werent)
To be fair I know exactly what you mean re Cue Card but you have to consider how the race was run.
Joe Tizzard rode a very sensible race that day. When Sprinter Sacre jumped past Al Ferof and pulled himself to the front Joe never panicked and chased after him immediately he just sat there conserving energy hoping that Sprinter had gone too soon. He soon realized that Sprinter was showing no signs of stopping and then asked Cue Card for his effort. Barry in the meantime is not getting after Sprinter Sacre knowing the only thing that might stop him winning is the hill.
So you have one horse flat to the boards and another one holding a bit in reserve which allows Cue Card to get within striking distance.
But when Barry does ask him to quicken after the last he actually starts drawing away from Cue Card again.
If Barry had said stuff it and asked Sprinter to go into top gear coming down the hill I doubt if Cue Card would have gotten within 10 lengths of him.
It's not just adulation form the media and punters Sprinter is getting. Like Arkle back in the old days trainers are avoiding him like the plague.
Cue Card,Al Ferof, Menorah and even his Stable companion Finian's Rainbow are all being stepped up in trip and their trainers think it's a complete waste of time trying to beat this fellow.
When did a 2 mile champion chaser ever not go back for a second go when he could have. I reckon you have to go back to Flyingbolt if you dismiss One Man who was actually going the other way.
No matter what the betting may indicate the only way Nicky Henderson will run Finian's Rainbow against him is if Finians fails to stay longer trips which must be doubtful after Aintree. He'd rather be winning the likes of the Ryanair again that finishing 2nd to Sprinter Sacre and his owner was adamant he'll never run at 2 miles gain as long as Sprinter has 4 legs and a a tail.
You may not think he deserves all the adulation but he's getting it and more because many people see in him what they saw in Arkle almost 50 years ago.
Maybe he'll never reach the heights people expect of him but we can but dream because to real racing fans it's horses like him and the anticipation that makes National Hunt racing the most exciting sport on the planet.
