billy was in same barn as stein many yrs ago. back when roy brown(billys stepdad) was alive. ole roy was a hell of a horseman.
im sure stein has his own connections. im not saying they may not help one another out, but i dont think either guy needs the other to do well. stein come from the plano training tree. billy comes from the roy brown training tree. and it doesnt hurt to have a vetrinarian wife.
