Evan Engram
Most likely the best tight end that could be available is Evan Engram with the New York Giants. The Giants are struggling after going 1-5 to open the season and they are likely going to be sellers at the trade deadline in hopes of adding draft capital for the future.
Since the Giants selected Engram in the first round of the 2017 NFL Draft, he has been producive with over over 40 receptions every season and at least 460 receiving yards and three touchdowns. However, considering the type of talent he is and what he brings to an offense, these are certainly underwhelming numbers.
While Engram is not officially available David Carr has recently said that general manager Dave Gettleman needs to consider it. If the Bills want to make a big splash, trading for Engram gives this offense what they hoped they would get from Dawson Knox only a better version.
