1. Don Hutson
2. Howard Cross
3. Lamonde Russell
4. Ozzie Newsome (Because he was a part-timer)
The correct answer is Don Hutson. He was a tight end. Saying he was a wide receiver is pure ignorance; there were no wide receivers when he played. He played platoon ball - all 11 players playing both ways - and was among the nation's best at everything he did: blocking, running, catching, tackling, and punting.
He effectively made the passing game what it eventually became, having designed passing routes that are still used today.
