So is OBJ. This is a 9 week rental. He is going somewhere for 9 weeks to reestablish is value. He doesnt care who is going to be where next year. Its HIGHLY unlikely he commits to anyone beyond these 9 weeks. It makes NO financial sense for him to do so with his value right now.
If he picks here, its not because of the 9 week money. Its because he believes the sheer volume of targets with a backup qb outweighs going somewhere with a legit QB and sharing targets with Metcalf, Adams, Hill, etc. in order to set him up to negotiate a long term deal in the offseason.
