‘2. Buffalo Bills: The Bills are too unproven to be in the conversation for best NFL trio — for now. We can justify the argument if we base it on how well they could be. But neither Jackson nor Lynch has established himself as go-to back. Jackson topped 100 yards two times last year. Aside from trampling the Indianapolis Colts’ junior varsity in the season finale, Jackson rushed for more than 70 yards twice against a team with a winning record. Lynch looked like a monster his first two seasons then plummeted out of favor last year. Spiller doesn’t have an NFL touch.’
