I don't see it as "too good of a deal", considering that (I believe) a lot of people like to transfer directly to Delta for simplicity (or bag/status perks). Delta miles usually aren't that valuable. Avios are.
Green is just a remarkably bad (prime) card, and not a good comparison candidate to determine what is a great one.
In my own opinion, there have to be a ton of people paying interest to Citi on their Double Cash card. MasterCard charges a 2% swipe fee on their cards, and if Citi is giving people 2% cash back with no annual fee, then Citi has be approving a lot of people that will carry balances to make this thing a profitable investment.
