This breeding (Mozak) is an A True Nick's rating, and the Indian Charlie over AP Indy rated cross is certainly proven. Liaison and Wilburn are the two best stallions standing in OK.
The pedigree matchup is interesting with Wilburn as it creates a 3x3 AP Indy over himself (sire to broodmare sire line), but like Storm Cat over himself, AP Indy over AP Indy historically does not do well.
The Liaison - Today's Treasure breeding on paper is really interesting. It creates a 4x3 sex-balanced to AP Indy through the unraced daughter Indy Flash who produced two graded stakes placed daughters (Galloping Gal - dam of Liaison, and Khalila.) Both daughters from Mr. Prospector line mares (Galloping Gal from Fappiano line and Khalila from Gone West line.) AP Indy has historically done extremely well over Mr Prospector and specifically over Unbridled (i.e Unique Bella, Malibu Moon, Congrats, Flatter, Mineshaft, Tomisue's Delight, Super Saver, etc.) So inbreeding to AP Indy with the extra influence of Victory Gallop and Unbridled's Song will even add additional affinity in this breeding - and of course Unbridled's Songs broodmare sire is Caro, who is Liaison's direct sire line. Another note of interest is Liaison's 4th dam Pet Eagle is by Raise A Native over Nashua, which make sure a 3/4 sibling to Mr. Prospector (also Raise A Native over Nashua.) This may be another reason Liaison seems to have an affinity to Mr. Prospector line mares.
Liaison's two stakes winners are Moonlight Romance and Bronx Beauty, and Moonlight Romance's broodmare sire is Malibu Moon, and Bronx Beauty's broodmare sire is Unbridled's Song - so it looks like what I stated above is supported by Liaison's two best offspring. And, of the seven black-type horses Liaison had in 2018, 6 of the 8 are from AP Indy or Mr. Prospector line mares with three of them supported by Unbridled's Song or Fappiano close up in the pedigree.
In conclusion, this is an A True Nicks rating, with a 4x3 sex-balanced inbreeding to AP Indy, sex-balanced 5x5 to Caro, a 5x5 to Fappiano, and a sex-balanced 6x4x6 to Mr. Prospector. The breeding also creates a nice tri-pattern breeding of Caro/Fappiano/AP Indy over AP Indy/Fappiano/Caro. So plenty of chances of these phenomenal genes pushing forward in the pedigree. This breeding also produces a potent 18 crosses to Nearco and 17 crosses to Nasrullah and 4 crosses to Secretariat's dam Somethingroyal through 9 generations.
As stated above, Liaison is getting precocious 2-yr olds, just like Uncle Mo. He is a big and powerful sire and will put a lot of speed in his mares. Today's Treasure is big and powerful herself, and did her best running at a mile. I would have like to see her extend to the 1 and 1/4 mile distance, which is where both Mineshaft and Unbridled's Song's offspring excelled. This breeding should produce a dirt 7 furlong to miler type that could extend easily to the 9 to 9.5 furlong range. So 7 to 9.5 furlongs on dirt.
