For me it would be too hard to call. I do not think I could actually do a top five because the #6 guy is just about as deserving as the first five. I am partial to the Redboy dogs. Redboy had as much impact as any other. Redboy himself, then the Medlins Outlaw strain. There is no Redboy-Jocko without Redboy. There are no Cottingham dogs. Whitleys. Robinsons. Marlowes. Hollands. Mims. Baileys. No Mayday dogs. No Jeep-Redboy dogs. The list can go on and on.
With that said. I could start with Bolio and get to the Buck dogs and do the same. Or with Dibo. etc. etc. The Eli family tree as well. I could not say any one of the major families has had any more impact than the other, nor their breeders. If I said Patrick, he would have a large amount of support and at the same time he would have just as many detractors. Same with Beaudreaux. Carver. Tudor. Mims. Interesting topic though and I look forward to others opinions. I sort of fence ride on this one. EWO
