Fred Warner has no versatility. Harvey Langi didn't play multiple positions for Bill Belichick. Michael Davis can only cover in the 5 different systems he has had in the NFL, not in college. Francis Bernard was a terrible athlete when not coached by the right guy. Kai Nacua could only read offenses with Bronco as the coach. Corbin Kaufusi had no chance without a specific coach. The list goes on and on. Not to mention Taysom Hill, Jaren Hall, Jamaal Williams, Matt Bushman, Brady Christensen and others there for the offense.
