4. Coby Fleener Indianapolis Colts
Yet another 27-year-old free agent TE who had a much better year than the others mentioned, pulling in 54 catches for 491 yards and three touchdowns. Fleener can get downfield and make plays, and he would add a dimension to the pass game that could see him put up big numbers in a Steelers high-powered offense. Fleener has 183 catches for 17 scores in his NFL career to date, and his addition would give the Steelers a legit tight end catching threat for sure.
