Casey Toohill
Similar to defensive tackle, the Bills needed to replace some depth at defensive end with the departure of Leonard Floyd and with Shaq Lawson not being re-signed. One of those players that will help with the depth is Casey Toohill.
Toohill was a former seventh round pick by the Philadelphia Eagles but didn't last long, in fact played only one game his rookie season with the Eagles, before joining the Washington Commanders. In the past three seasons, he has started 14 games but was most productive this past year with five sacks and seven QB hits, both career highs.
He is a smaller defensive end that is able to beat offensive tackles because his quickness and athleticism. In this defense, the Bills can really maximize his skill set as they rotate four, to some times five, defensive ends during a game.
However, the Bills would draft Javon Solomon after signing Casey Toohill and both seem to fill the same role. It would make sense for both to be on the 53-man roster but likely only one is active on game day. If Solomon shows some potential his rookie season, the Bills probably will let Toohill leave in free agency at the end of his contract this season.
