It’s widely held belief that a good draft class should yield two solid starters. Two starters may not be a great draft, but it is certainly a solid draft. However, those two starters are not necessarily expected to be starters in their first season.
The 2018 draft class hasn’t played a single regular season snap yet, so it’s way too early to start counting potential starters from this draft class. Sure, Connor Williams looks like he’s a lock to start at left guard, but it quickly gets sketchy beyond that. Leighton Vander Esch and Michael Gallup are likely to get some starts this season, but they will probably not be day one starters.
