After the death of Glazer was confirmed by the Buccaneers, the duo spoke out on the man who has owned the team since 1995.
Gruden told the Tampa Bay Times: "He was a genuine, hard-working, one-of-a-kind man. He was a friend, a trailblazer and I'll miss him."
Meanwhile, NFL Media analyst Sapp said: "As the first ever pick of the Glazer family, I'm proud to be that pick and I'm very saddened at the hearing of his passing.
"He was a true giant as a NFL owner and I was proud to call him my owner and boss plus a friend! I love the family."
Glazer was 85 years old and was also the owner of Manchester United.
