Obviously. But if keeping Chappell healthy for GVSU was of utmost importance, why not sit him and play Murray against WSU? Why risk additional injury to Chappell at all? Perhaps Lennon was concerned about the message such a move would have sent to the team.
I could see sitting Chappell for the second half if Murray was healthy or if Brady was available. But that wasn't the case. With the game still on the line, you need your best players to go out an make plays. And the game had not been decided at that point.
Yes, UND's defense was playing well, but if you listened to what Lennon said leading up to the WSU game, he was very concerned about the Warriors' offense. Knowing that all it would take was a couple of big plays to get WSU back into the game and knowing that UND's defense has been giving up big plays routinely, my guess is that Lennon felt the Sioux needed to keep putting points on the board.
But you see, using 20/20 hindsight I can say that Lennon was wrong to have played Chappel at all because the Sioux defense played great and all UND needed to win the game was one field goal.
