Vamdeberg had 384 yards last year. Smith-Marsette and Brandon Smith COMBINED for 202 yards last year.
To say your WR group will lose their second best player and add nobody of significance and still manage to go from the worst WR's in all of power conference football to solid and consistent is laughable
So using your logic, Iowa State’s OL will suck again this year- they add nobody of significance, after all. Apparently there is no possibility whatsoever that any of the returning players improve.
