So the offensive line could all return although it wouldn't surprise me if Hoge & Kramer both compete for starting jobs. Here's a quick look at what the OL looks like.
LT - McGlinchey
LG - Nelson
C - Mustipher/Hoge
RG - McGovern/Kramer
RT - Bars
There is a lot to like in that unit. They took their lumps at times in 2016 but I think Kramer ends up starting and will be a pretty large upgrade over McGovern. Bars with another year should be vastly improved too.
