Conflict diamonds are diamonds that are illegally mined in Africa using modern day slave labor. They are then sold on the black market for a lower price than certified diamonds. Usually they do not make it into large diamond brokers, however the system is not perfect and sometimes larger jewelry chains will unknowingly purchase these stones.
Conflict diamonds get their name from the fact that the warring tribes in charge of the mining operations usually use the money they get to purchase weapons and to fuel their "conflicts".

Did George Atkinson hit harder than Jack Tatum?
I don't believe George Atkinson hit harder than Jack Tatum, but he could deliver his share of intimidating and by today's standards "Cheap shots" E. G. breaking Russ Francis nose in the 1975 playoffs against New England in Oakland, it was a vicious hit. What made George Atkinson so fearful in my opinion is that he was part of a tandem of hard hitting defensive backs, imagine going down the middle and wondering who you will be hit by first, Willie Brown, Jack Tatum or George. Neither choice would instill much pleasure into any tight end, running back or receiver, even by today's standards.
