"....It's going to be a really tough assignment for our guys because they are actually really good ball strikers and they will be dangerous.
"They're a lot better than they're ranked...."
That is wrong. They are ranked that because they can not win matches at Challenger / Tour level. What Rafter does not recognise is the depth of Men's tennis in this era.
Millman, ranked in the 200's beat Ito ranked mid 100'2, Jones beats Hanescu ranked 99 and then Melzer, ranked 29, then loses to Statham ranked 340.
At this level it depends on conditions, balls, surface.
This should be recognised.
Also, they are going to get Leytton injured again by playing him too much. It has happened previously, twice or more, and one hopes they (TA DC) have learned from experience.
