Like other poster have already stated, Carter is a lot bigger than Werner, 6’3 260ish. & as for his ability vs the run, the dude was an off ball LB his entire career before they converted him this year into a true EDGE. So he’s actually well versed against the run, & the part of his game that actually needs refinement is his pass rushing.
That being said, Carter had 12 sacks & 24 TFL from the EDGE. This dude’s potential matches his production. If he somehow fell, or fell close enough to trade up for, i pray we make that move. Abdul Carter is a player you can build a D around & we’d be blessed to land him.
& the Vic Beasley comp fits James Pearce more than Carter. Pearce is the player i worry about for all the reasons you used to describe Carter.
