Buffalo Bills center Eric Wood has admitted that facing his side's defense in practice has helped them prepare to face the New York Jets on Sunday.
Bills defensive coordinator Mike Pettine was with the Jets for three years in the same role and has brought a lot of the scheme with him to Doug Marrone's side.
Wood told the club's official website: "We feel it's an advantage that we've seen this all summer.
"There are some differences, but some of the looks are the same and some of them are tough to prepare for so having seen these all summer has made some of the assignment installation easier."
The Bills are 1-1 in their season going into week three.
