Melton and Okoye have both looked extremely good this offseason at the 3-Technique so barring injuries to either of them, Paea's best chance to get on the field is clearly as the other DT. Which puts him in competition with Anthony Adams and Toeiana as well as Marcus Harrison (if he survives the cuts), so that's gonna be an uphill climb for Paea this year anyway, I think.
He'll make the final 53 no question, but how much playing time he actually gets remains to be seen.
