Thats also a lot of your rotation. Plugging 1 player into a rotation is one thing - now you have all these changes
Addison and Hughes play the same side - 1 will play out of position no matter what on passing downs.
Oliver is still the primary 3T still - but the 1T is phillips or jefferson. Jefferson would be out of position there on rushing downs.
Jefferson may also rotate at DE with addison and hughes. Lot on that guys plate. Epenesa stepping up could give Hughes and addison some breathers, while also giving hughes some snaps on his natural side.
Butler should be a rotational 3T but they are likely to have to play him at 1T since Phillips has struggled so badly.
So even with new faces, its just a lot of turnover. No preseason, fewer practices.
