Cliff really hit the nail on the head in terms of "it depends".
We have a Lord granddaughter with bad hips (moderate HD), a host of mild to moderate nerve issues, mediocre drive, very soft and handler sensitive but at the same time quite independent and not at all biddable, possessing absolutely none of the tracking talent or hunt drive typically seen in these lines. What aggression she has is completely fear based, and while she's quick to alert bark beyond that her coping mechanism for any form of pressure or threat is to run and hide under the bed. Great with other animals and very social with people in general, but iffy around children (they make her uncomfortable) and dog aggressive. She has a totally wonderful, sweet, in many ways comical personality in general and is a fantastic pet. But certainly not a working dog in health or temperament, and of course was never used for breeding. I've seen many, many other dogs out of her sire (a Lord son) with various degrees of the same issues except the tracking. Overall the others I have seen are excellent trackers. And like her, by and large wonderful general personalities making them good companions but in many cases no more than that.
Our foundation bitch was a granddaughter of Fiasko, so a Lord great-granddaughter. Strong, but certainly not extreme drives. Very balanced prey and defense, and would show good aggression if given a good reason to. Phenomenal tracking and hunt drive. Excellent health and hips. Very biddable, compliant, handler focused nature. A bit on the softer, handler sensitive side, but extremely resilient and totally environmentally sound. Nothing phased her. Wonderful with people, kids, other dogs, cats. She produced extremely well, with many excellent working dogs (and excellent pets) amongst her offspring, and now grand offspring.
2 dogs going back on Lord fairly close in the pedigree, yet 2 very different dogs with very different things to offer. It most certainly came down to what that Lord was mixed with in their pedigrees.
