The only guys they can put at DT are Hulak, Sevillano, Burgess, or Dixon. Hulak is still way too small - he came in at 240 and does not have a big frame. The coaches were going to move Dixon to OL, because he is not quick enough for defense. Burgess is far better suited for DE - no one recruited him to play tackle. He’d have to put on too much weight for his frame. Sevillano is a possibility, but he has been injury prone and lacks quickness to be a DT - More of a Nose in a 5 man front.
They may have to play Golden and Hola as freshmen, which is not ideal. They both need time in the weight room.
