Anything Over 6 or 7 wins with Winston at Qb would be considered a win
Look at the NFC teams that finished with 6-8 wins last year:
Washington Football Team - 7 wins
Giants - 6
Cowboys - 6
Bears - 8
Vikings - 7
Cardinals - 8
49ers - 6
Talent wise I'd say we have as much or more talent than those teams overall. If the Bears can reach 8 wins with the combination of Trubisky and Foles then I'm sure the Saints can reach 8 wins with Winston and a 17 game season.
