4. Trent Green (overrated)
How in the world did Trent Green even stay in the NFL for a full decade? The best thing he ever did was get hurt so that Kurt Warner could take over and lead the Rams to the Super Bowl in one of the greatest stories in NFL history.
He spent five years in Kansas City after the Chiefs gave up a first-round pick to get him, but he only had two winning seasons in those five years. For much of his career, he was the least-worst option his team had at the time. Even calling Green an average quarterback seems like a compliment he doesn’t deserve.
