'The Bills are likely to go defense when they make the 19th pick tonight, with filling a hole somewhere in the front seven a top priority. The Bills are going all-in on Rex Ryan’s 3-4 scheme this year, but the linebacker corps as it stands today is one of the thinnest positions on the roster. Bradham is an Eagle, A.J. Tarpley retired and Tony Steward was cut. Manny Lawson and Preston Brown are the only returning backers who made any impact in 2015, and Brown’s sophomore season was uneven.'
