Except he really wasn’t. He was propped up because he came from Notre Dane, who is notorious for producing quality lineman. He had a good combine and pro day that really helped his case too. However his tape showed the obvious flaws. In shorts and tshirts he look agile and fast, but in pads he looked awkward, a bit slow and clumsy (footwork). It was especially evident against anybody with speed. He also lacked punch and wasn’t able to anchor very well. They thought strength training would help this. Help, sure, completely reverse a severe problem ??? Unlikely. His training camp weigh in will tell slot. If he’s still around 305 and playing guard, it’s game over, the strength training obviously didn’t work.
I can appreciate the hope and optimism, there are plenty of other reasons for it. However Eichenberg is who he is, a guy who’s ceiling is bottom tier mediocre or complete replacement level.
