Zeller was one of the more productive offensive linemen of the Edsall era. Despite not being a very highly sought-after recruit, Zeller started every game for the Terps during his junior and senior seasons. The Maryland guard offered tremendous stability for an offensive line that saw several different quarterbacks take snaps under center.
The Lions have addressed the offensive line in the last two drafts with Taylor Decker this year and Laken Tomlinson last year. Tomlinson and Larry Warford are the expected starters at the two guard spots, so it’s highly unlikely that Zeller would get any considerable playing time if he cracked the roster. Veteran Geoff Schwartz is also on the roster along with fifth round pick Joe Dahl and Darren Keyton. The deck is certainly stacked against Zeller making the team, but offensive linemen can latch on just about anywhere in the NFL. If Zeller has a decent showing in the preseason, he could get picked up by another team in need of offensive line help or land on a practice squad.
Aside from Ross, Zeller probably has the slimmest chance of making the team he was signed by. Zeller definitely has the talent to land on an NFL roster. The question is going to be if he can showcase his ability in the short term that is the NFL preseason.
