I thought he looked pretty good at 270 but read that he'd actually gained weight afterwards.Eason is 270 and doesn’t have Sewell athleticism. He’s not playing ILB unless he loses 25 lbs. He will be an OLB or have his hand in the dirt if he keeps growing.
I guess it depends on his muscle mass as much as his weight. But your basic point is spot on. He has to be able to move or else he has to play Jack/DE.
