Which would u rather have a Pocket qb?? or a scrambler qb?

Id use the term mobile.Dan Marino wasn't a scrambler(lol really)but was mobile within the pocket.I'd want someone who could do a little more than as it adds another element the defense has to consider.Pure pocket pers need as a #1 priority protection and without that cannot function.Scramblers are too 1 dimensional and in the NFL will ultimately fail.
