I think the key in this situation is to seperate what the coach actually said from what the writer elaborated with. You might believe we should move farther away from the option and you might think Rivera did mean that. However, Rivera absolutely did not say that.
A member of the media asked a standard question regarding if they were going to make up for missing KB by using more option. He said no and it would not be used more than in the past. I see nothing that suggests they are continuing any trend or using it less. Rivera said nothing about that in the linked article. They arent going to say a word about their strategy. I agree.
Slot and #2 are not comparable terms. Football players and coaches speak in terms of x,y, z. Fantasy football talks in terms of 1, 2, 3. A slot receiver can just as well be a fantasy 1 or 2. Look at Welker with the Pats. Funchess could be a slot receiver.....given KB was playing and still be a #2 Fantasy receiver.
