Buffalo's 2025 rookie grades after four games reveal a broad range of impact. Hairston sits with an incomplete due to a knee injury and a 21-day practice window looms. Sanders has shown pass-rush potential with six QB pressures but no sack yet. Landon Jackson has stayed healthy but hasn’t earned a jersey. Deone Walker has been the standout, flashing both 1-tech and 3-tech versatility. Hawes has been a solid contributor as a blocking tight end with receiving upside; Hancock and Lundt have limited snaps; Prather was waived after an injury. Ed Oliver's injury has shaped the defensive rotation, and the Week 4 Saints game offered a clearer view of Buffalo's depth. Beane’s class blends immediate depth with upside, even as some top picks wait for a window to contribute.
