I think it does carry weight. I don't think it's a guarantee by no means but I do believe in percentages and more hot pups turn out to be good dogs be it box/brood or both than don't GRANTED he/she doesn't have an impatient/wreckless owner. I've seen it on my own yard and other fanciers yards. I feel a hot pup is like a hot head 16 yo athlete . They think they grown but they need maturing. There's been plenty young athletes on the professional level thought they were good but when they matured and listened to they "GOOD" coach they became great!
