The Buffalo Bills officially announced the hiring of six coaches to Rex Ryan’s staff: Michael Hamlin (special teams quality control), Aaron Kromer (offensive line), Sanjay Lal (wide receivers), Anthony Lynn (assistant head coach/running backs), D’Anton Lynn (defensive assistant) and Chris Palmer (senior offensive assistant).

Kromer spent the past two years as the Chicago Bears’ offensive coordinator, and came under fire after admitting he was the source of criticism toward quarterback Jay Cutler.

The Bills also announced that Kurt Anderson (assistant offensive line), Donnie Henderson (defensive backs), Jason Rebrovich (outside linebackers) and Jason Vrable (offensive quality control) will be retained.
