Watson is not a fad. He runs because he has a poor offensive line. Give that kid protection, and he'll kill you in the passing game. I thought Dabo was blowing smoke when he compared Watson to Michael Jordan. But seeing Watson play, he is more talented and more gifted than I gave him credit for.
Jackson is likely to have a short career, ala, Slash/Kordell Stewart. He won't be able to run like that for many more years. Either he's going to have to develop throwing from the pocket, or I'm giving him 3 more years of running as a quarterback - MAX! But maybe the Ravens think they'll get a Super Bowl out of him, which may be worth it.
