I know that Hill is fast, but if he was the fastest guy on the team, then you would think that he would have had a play this year that went for more than 40 yards (which he did not). I know that he only had 37 rushes and 3 catches, so it's a smallish sample size.
Looking back on their respective senior years, from a rushing standpoint, they were pretty similar. Hill with 137 carries for 603 yards (4.4 avg) and 8 TD's and Dungey with 184 carries for 754 yards (4.1 avg) and 15 TD's. From a passing standpoint, Dungey had 550 more yards passing on 1 more attempt, with 18 TD's and 9 INT's versus 12 TD's and 11 INT's for Hill. I know that 40 numbers mean a lot, but if there is a spot in this league for Taysom Hill, then I could easily see there being one for Dungey.
