Last year Tate got 263 carries, with McCalebb a distant second with 105 carries. However, we also had Fannin with 76 touches (698 yds), Burns with 56 carries (175 yds), and Eric Smith with 38 touches (325 yds).
If we intend to run even more plays (and the above list totals 538 touches)...there will be plenty of touches to go around to Aycock, Fannin, Smith, McCalebb, and Dyer.
One note on Fannin, and why I still think he belongs in the backfield carrying the ball, not catching it in space. For some reason, when Fannin catches in space, he takes too long getting down field and tries too hard to make every catch a huge play. He averaged 9.8 yards per catch. Compare that to Eric Smith's 12.6 yards per catch. Smith catches and immediately heads north-south and gets down field.
However, from the backfield, Fannin is much better at just getting up field. He carried it 34 times for 285 yards (that's 8.4 yards per carry with a long of only 32 yds, so it wasn't skewed by one 90 yard run or anything).
Anyway, I see Malzahn getting the ball in the hands of all five of these guys anywhere from 75 to 190 times each.
The five guys from last year got 589 touches. I don't see Kodi continuing his 3 yard per carry wildcat role. However, if Newton does become the starter, he'll get those carries I'm guessing (and maybe more).
Taking Kodi's 61 touches out of the 589, and assuming we run a few more plays, let's figure 550 touches for the five guys listed for next year.
Aycock - 190
Fannin - 130
Dyer - 80
Smith - 75
McCalebb - 75
This is a completely made up scenario, but it just shows how many touches there are to go around. Regardless of the breakdown of who gets them, everyone will get a chance to get involved.
