There's no doubt that it's a slight concern as Posluszny saw his tackle numbers drop this week in what was a very favourable matchup against the Ravens.
The important thing to remember here is that long term, Posluszny projects as the WILB in the Bills 3-4 scheme. The 4-3 may be a temporary measure, and in all likelihood it will be. The Bills drafted Torrell Troup to be the NT in their new 3-4. Anything could happen, but Posluszny should stay productive. Just temper your expectations slightly.
