After the season 20 transfer period came and went with not a single signing Greensboro fans started to question owner Chris Fields committment and thriftyness.
Those questions were quickly answered.
Greensboro cemented its weakest area just a few weeks into the season with two key signings.
Defenders Rogelio Paez and Matias Tevez were signed by the Vipers to five year contracts.
Paez, one of the most saught after defenders in the league, signed for a modest $612,000 per season. The former Galway FC defender and Argentinian adds immense star power and talent to the defense.
Tevez, also Argentinian, aso signed a bargain deal of $253,000 per season. Tevez was also a saught after defender who formerly played for Galway, as well as a short stint for the Lexington Lions.
These two deals have Greensboro fans going from booing to ooing.
The Vipers D has gone from being maybe its weakest unit to being undeniably its strongest.
Opposing teams face an uphill battle when attacking the Viper's back line this season.
