The 2017 Offensive Rookie of the Year is... George "Hubba Hubba" Hubert! Since Hubert won MVP, and rules dictate that any other awards that the MVP wins become Co-Awards, the Co-OROYs of the 2017 MFN-83 season are Hubba Hubba Hubert and David Murch, players for the Washington Phoenix and San Francisco 49ers, respectively. Look at the MVP page for more info on Hubert. Murch got 90 receptions for 1,603 receiving yards and 9 TDs, a great start to a WR's career.

Honorable Mention: Keith Quayle
Quayle played a key role on Cincinnati's offense as a hybrid WR/RB, with 1,103 yards from scrimmage and 6 touchdowns. He had 5.2 yards per carry for 851 rushing yards, and 12.6 yards per reception on 20 catches for 252 receiving yards. Had he been more-fully integrated earlier on, I believe he could have ran for over 1,000 yards (still at around 5 YPC) and received for over 400 yards.
The odd men out are Josef Jaeger, the QB for the San Francisco 49ers and Tyler Newkirk, the RB for the Dallas Cowboys.
