In what could be described as both an upgrade and a "payback" to the Patriots off season attempt to pry away wide receiver Emmanuel Sanders, the Steelers have signed punter Zoltan Mesko and released punter Drew Butler. Mesko brings with him a career 44.2 yard average in three seasons with the Patriots . Butler in his one season with the Steelers averaged 43.8 yards per punt. Mesko brings a much needed upgrade to the punter position and should definitely help out the Steelers special teams. Mesko in 2010, punted 58 times for the whole season as the Patriots were the 7th highest scoring team in NFL history. Of those 58 punts 19 of them were downed inside the 20 yard line. This of course was in his rookie season. Mesko's price tag with the Patriots was 1.323 million, which right now probably answers where the 1.3 million from Dwyer's release is going. Also in other transactions , the Steelers signed Antwon Blake a cornerback from the Jacksonville Jaguars. Blake was signed by the Jaguars as an UDFA in 2012 and played all 16 games last season. He led the Jaguars with 12 special teams tackles. The Steelers released cornerback Isaiah Green , who is expected to be reassigned to the practice squad after clearing waivers, signaling the end for cornerback Devin Smith.
