By emerging talent you mean currently on the roster? If so, Lamarr Houston, Marcel Reece and Tyvon Branch show the most promise out of guys that are supposed to be with us long term. And Jared Veldheer. Other guys the jury is out on but there's guys with potential.
As far as DA and Reggie go, I can't give a final say on either yet, like to see what they pull next year. If they show no progress then I'm ready to move on. I'm not a fan of Reggie's draft choices thus far but a few of the guys (Moore, Hayden, Watson) haven't had enough time to break out yet but have potential.
