... If anything they should keep Bullock at WR and maybe give Canzeri his carries, but no way you take away Weismans carries unless you're giving them to Daniels...
First off I am amazed that we are actually going to be able to discuss natural distributions using Iowa's running game! After years of legendary RB attrition this is a great situation to find ourselves in.
There was an interesting thread a while back, maybe here or linked from here, about total team yardage and what is the optimum number of players getting rushing touches vs. maximum individual stats. It looks like this could play out here. Today we had almost a perfect 50 percent distro w/ Weisman getting just shy of 52% of the carries. For any individual player to get a maximum number of yards and increase the team's total yards we need a classic 60 percent distribution (top rusher gets 60% of carries).
The interesting thing, IIRC, was that optimum number of ball carriers was 5. Today we had 6 carriers so we have an odd man out, WR Damon Powell, w/ 1 carry for 2 yds. What's also been missing in this discussion is the amazing fact that our #3 rusher is our QB!
Looking at efficiency (yds/carry) as the main factor, and if we ignore the outlier Powell and give his carry to Weisman, Bullock was the least efficient at 4 yds/carry.
So if a 60% distro is the goal then Weisman should have had about 4 more carries and our #2 rusher should have been Daniels w/ 13 carries.
Rudock would stay at #3 w/ 6 carries, so he looses one to Daniels.
Canzeri would stay at 3 carries and be the #4.
Bullock would give up 8 of his 10, to be redistributed to the top 3, to take the #5 slot. Moving him into the slot makes sense in this scenario.
This would yield about 318 yards on the ground, up from the 296 we saw today.
Of course this is just a numbers exercise and it can't be planned in this detail because Rudock is going to see exploits and be involved in plays that breakdown. That will increase his carries. Canzeri could move into the #3 spot if the play calls favor his speed on the outside and he ups his yds/carry.
Iowa has the reputation of being a run first team and has had an upper tier rusher for most of KF's time at the helm but the stats show this is mostly perception and not reality. Today the stats show something different. Iowa's rushing game was #2 in the B!G today. Only Whisky rushed for more yards as a team. Canzeri will probably never get as many carries as he wants but he certainly can contribute to a more dominate Iowa running game.
I 'm not sure what the optimum distribution is for receivers but he could also contribute out of the slot and, as others have mentioned, on special teams as a return man. There are probably distributions for the return game too.
