Andrew Van Ginkel, Zach Sieler and Myles Gaskin stand out as the biggest Miami Dolphin improvers of the 2020 season. Incidentally, Van Ginkel was drafted in the 5th round, Sieler was drafted in the 7th round by the Ravens and claimed from their Practice Squad and Gaskin was drafted in the 7th round. Getting terrific value from late round Draft picks is one of the steps in building a successful team (pat on the back to GM Chris Grier). All 3 are keepers.
BTW - Jason Sanders looks like a pretty good 2018 7th round Draft pick out from the University of New Mexico Lobos.
