I don't expect the Saints to have All Pros and Pro Bowlers as backups to All Pros and Pro Bowlers, but no one can deny this offense died when McCoy and Hill got injured. They couldn't overcome two players getting hurt. That to me is unacceptable and why while I don't like the idea of trading critical future assets for Adams, at the same time it is clear why it makes sense to want to get Adams.
However after the additional injuries Monday, I think it would be downright stupid for the Saints to go get Adams right now. They should wait until the trade deadline, see what the record is and get Adams for as cheap as possible if the Saints still have life. If the Jets with no Head Coach and no future at QB want to beat the Saints to the punch and trade their future assets for a soon to be 32 year old WR, they can go right ahead. If a team like the Vikings or Commanders feel Adams will put them over the top, it is what it is. If the Saints are 4-5 at the deadline, sure, I'd absolutely make a play for Adams even if it involves a 2nd. But if this skid continues and the Saints show up at the deadline with a 3-6 record? No way.
The Saints with Ireland have been phenomenal in the first two rounds of the draft. A 2nd round pick for the Saints is drastically more likely to be an 8 year starter than a bust. That's not something you just casually brush off for a WR who will be 32 before the season ends.
