The Dallas Wings offense struggled for the second game in a row, but some steady fourth-quarter defense secured a 76-64 win over the Atlanta Dream on Saturday.Dallas (2-2) shot 37.9 percent from the field, up just barely from the 34.6-percent shooting mark in Wednesday's loss to the Minnesota Lynx. It was a far cry from the 101-point performance the Wings produced against the Dream a week ago.The Wings' play on the defense end evened things out.
