Since a 4 TD game (with 3 INTs) with 361 yards on Oct. 20, Dalton has trended downward with 229 yards, 210 and last week just 174 against the Steelers. He's thrown four TDs and three INTs in that same three game span. You can argue it's a little surprising the team didn't make the switch following the loss to Pittsburgh, so Dalton could be on a short leash assuming Winston is ready to go.
NO QB Jameis Winston - Week 4 Fantasy Football Outlook
Week 4 vs. Minnesota Vikings (London)
Jameis Winston's status for Sunday game against the Vikings in London is up in the air as he did not practice Wednesday or Thursday. He is still dealing with his vertebrae fractures as well as ankle and hip flexor injuries. If Winston cannot go this week, it will be Andy Dalton leading the charge. Either way, no Saints QB is worth a start this week. Winston did throw for 353 yards last week but also threw two interceptions and has five in the last two weeks. There's too much concern here.
Update: Winston is doubtful to play Sunday, so it would be Andy Dalton starting if Winston cannot. Dalton has very little fantasy value and managers should look elsewhere if possible, although if Taysom Hill is active and eligible in your TE slot, there's some upside there in deeper leagues.
