I don't disagree that Olave/Adams is a much better duo than Olave/Shaheed. But I don't think this OL is going to hold up in 11 personnel. They didn't against Atlanta. I saw a stat that Carr had like 2.3 seconds to throw and a lot of that could because of the increased use of 11. Anyway, while Adams would certainly be an improvement, I think it's a marginal improvement that wouldn't turn this team into a Super Bowl contender. Maybe it helps with the division, but I'm not sure one push for a Division title is worth the future cap implications, draft pick cost, or the fact that it likely leads to having to let AK go.
I also don't know how you pay a 32 year-old Adams who has 3 years left on his deal while refusing to extend Kamara. While it would be nice to have 3 good WRs, Kamara is the ONLY RB we have that is better than just a guy. It's just inconsistent with their current level of cap restraint and a pretty sheetty way to treat Kamara who is still a great RB. Adams is just as likely, if not more likely to decline in the next 3 years as Kamara is.
