I'm sure I'll be in the minority with this take, but I really hope that the Packers stand their ground on Adams and let him walk if they must.
If a reasonable deal can be agreed upon that doesn't commit to him too far into the future, then fine. He certainly deserves a raise. But if he wants cap commitment well into his 30's, pass.
Adams is a stellar talent and player. But this extension would start at age 29, at a time when the Packers are likely hitting the reset button at QB. I can see the argument that you want to surround Love with lots of expensive talent while he's still cheap himself, but I still see too much downside if you're committing to a wide receiver into, say, his age 33 season.
This isn't a quarterback, offensive tackle, pass rusher, or lock down corner... it's a receiver. Wide receiver is a dramatically overrated position. The entire game has been reshaped in the last 20 years to make their jobs easier. They're treated like a premium position, but they're at best 5th in terms of importance on the field. Don't over-invest.
