1) Because teams found better backs
2) so did many other good backs, that has nothgin to do with how good you are
3) This is false. in Freds best years he ran behind arguably the best o-line in the league at that time
4) This is kind of key to being good, being able to stay healthy.
If you were to place a pole of fans from around the league from every fan base, Fred Jackson does not make top 10. He is a loveable Bill. Much like Brian Moorman was. Fred Jackson, good running back, never a best all around.
