To be fair to Tony Mullins, I was at a preview last year in Portlaois and still have the notes on my phone.
What he got right:
"Yanworth won't beat the ambulance in Champion" - referred to this the last night and said he fancies him for stayers.
"Buveur D'Air better than Yanworth."
"Can't have Melon, but he'll beat bunk off"
"Limini lay of meeting, if she was right she'd go in Champion, something smelly about her this year"
"Let's Dance wins mare novice from here to Stradbally"
"Yorkhill is a man now, wins by a mile"
Naps - Yorkhill and Let's Dance
What he got wrong:
"Bacardys best horse in Neptune" - horse was badly hampered and won the grade 1 at Punchestown
"Scorpions have no guts, if Might Bite was 5L clear after last I would still lay him" - small bit of vindication here

"VVM wins mares"
"COC not a XC horse"
Advised Charbel without Altior, while technically a losing bet he was running some race.
Other:
Said he hadn't seen Willie as bullish about Djakadam in a long time.
