Streit is around on wire. He's been very mediocre with ample PP time. His +/- hurts his value as well in my league. Thinking Lubo may get that PP going and make Streit a worthy ww grab. Has Streit lost his special teams magic a couple years ago or can he again be valuable? Other options are Wisniewski, J.Johnson.
Streit definitely has good value, not sure whether or not Visnovsky helps it or not, but the value of Streit is definitely still there, with or without Visnovsky. Your league isn't probably to big, and I don't know your roster, but depending on the situation, he's probably worth picking up.
