Could I see it happening? Sure. Anything can happen? Do I think it’s likely, not exactly.
Odell isn’t fully healthy right now, so his agent is under no rush to get him latched on with a new team. It makes the most sense for Odell and his camp to wait to see how things shake out in the preseason - and possibly even into the start of the season - to see if a contending team suffers an injury or if a fringe team thinks the addition of Odell could make them a contender. At that point, the signing team, whether its the Saints or otherwise, would likely be willing to overpay for Odell to bring him into their offense.
