 Rookie Leonard Fournette  hasn't looked the same since spraining  his  right ankle against the Los Angeles Rams in mid-October.  He  ran for 181 and 130 yards in consecutive weeks against the Steelers and the Rams  respectively  and broke off long touchdown runs in both games.
 He 's topped the century mark twice — both barely — since.
