Give it a rest.
Unusual Heat's success at stud right now has everything to do with the synthetic surface invasion in California.
Back when I was young, California racing was always king when it came to dirt sprinters. They'd almost always kick the ass of Eastern sprinters when they'd ship. A big emphasis was placed on early speed .. and the Cal breeding program reflected that.
Unusual Heat was a Euro import. He ran fast figs in America - and Abrams basically claimed a horse with a huge glowing "For Sale" sign .. got 2 whole races out of him .. and got lucky with him as a stud thanks to synthetic tracks. The comment read "returned lame" in his 2nd start off the claim when he was back in for a tag. Abrams had him sound for a whole 19 days.
Here's a cut of form from some claimers turned stallions. I included Cozar - he's the Unusual Heat of Presque Isle Downs .. only difference is that his offspring have to run open instead of against state breds.
