He’s a much better player inside. Last year he was asked so much for a rookie and didn’t have any support and terrible coachingI felt like he regressed throughout last year honestly. I don't think that is his fault though. The coaching was garbage last year, and insisting guys play a strange ineffective technique will cause players to regress.
However, I do feel like Eich might not ever turn out as an above average player due to his size/athleticisms issues. He's got the height to be a tackle, but short arms and a lack of quick lateral mobility necessary to make up for those short arms, and his height is actually a large disadvantage inside at guard. He's the ultimate tweener, and unless his technique is nearly perfect, it's going to be hard for the guy to overcome that.
I felt he got better technique wise but the line overall was a mess and didn’t help him. I expect him to be really solid moving forward
