Will be a dereliction of duty if the front office does not get Winston help at WR before the trade deadline

Keep in mind this pesky thing called the salary cap. Ingram was had for essentially a bag of Zapp's chips, and I believe the Saints are only on the hook for roughly half of Ingram's $1.5m base salary.

The Saints only had $1.6m in cap space before the trade for Ingram. They'd have to be extremely creative with contracts to get any kind of wide receiver who can immediately impact the offense right now.
The cap hit for Ingram will be about $1.3 million. (I think game day roster bonuses count against the cap.) Allen Robinson is out of the question without some SERIOUS magic by Loomis. His base salary is $17.88 million. Cooks on the other hand would be a piece of cake for Loomising. His base for the year is only $2.5 million. Loomis could create a couple of million pretty easily.
