both Bruce and Faulk, but the level that Martz elevated when you look at the results are staggering for both.
Even if you pick Faulk's best season, he still went from a 4.0 YPC player to a 5.5 YPC player. 4.0 is done by a ton players ever year
that particular season, here are the 1000 yard runners that had an average of more than Faulks 4.1.
1) Terrell Davis
2) Garrison Hearst
3) Robert Smith
4) Fred Taylor
5) Jamal Anderson
6) Gary Brown
7) Corey Dillon
8) Priest Holmes
9) Barry Sanders
10) Warrick Dunn
11) Emmitt Smith
12) Marshall Faulk
in 1999, Marshall Faulk went from 12th to 1st of 1000 yard runners in Yards Per Carry. Hence a pro bowl type player, becomes and all-time legendary Hall Of Famer doing something that few backs in NFL history did. 5.5, 5.4, 5.3 in 3 consecutive seasons.
The increases in productivity in the average of his first 5 years versus the average of his next 3 years is some of the greatest spikes in NFL history of productivity. He went from a back that got yardage because of volume and default as 12th out of 30 teams in his very best season is good not great, to one of the best of all-time.
