I couldn't locate per-game fumble figures for Payton's period, but he fumbled 86 times in his career, which equals to 2.0 percent of his touches (rushing attempts + catches). Sweetness maintained his fumble rate under 2.0 percent in eight of his thirteen seasons. If we assume that pace continues, then Peterson will have 91 fumbles by the time his career is over. Peterson's fumbling rate was also below 2.0 percent in 2010 when he lost nine fumbles. The only other season where he lost more than four fumbles was 2007 when he had five losses. Overall, Peterson has fumbled 93 times in 206 games played (4.3 percent). The table shows that while some players tend to fumble more often than others, most fumblers don't reach the number of Peterson's fumbles in a single season. However, if you were to average his fumbles per game over 16 years, then you would get close to one every other game played.
