Almost EVERY FA signing is a grand overpay. Thats how it was meant to work. They dont get much the first 3 years. Then get a modest salary the next 3, then bank for however many years a team is willing to go.
With that said, besides the contract over by about 2-3M per, Im good with SV. Great D at ALL OF positions, good arm, good speed, good baseball instincts and good person. So, its all good ;)
