It's going to be interesting to see how the positional questions get answered for ND during the spring camp (and eventually summer/fall camps)
The key questions for each position are:
QB
1. Who is going to start?
a. Is this determined by 1 player absolutely seizing the role through great play or through neither player seizing it?
2. Is there going to be a multiple/situation QB role?
3. Is our QB position able to effectively grab the leadership role in the offense?
4. How much trust/timing can these QBs build with their receivers?
RB
1. How well does Folston recover from his ACL surgery (tore in ND/UT game in 2015)
2. How much do the young RBs improve (Adams/Williams)
WR
1. Who takes over the "stretch the field" role, vacated by Fuller?
2. Which underclassman are able to step up well enough to demand PT?
3. How much rotation and position mobility can the coaches get out of the players that step up?
TE
1. Will one player step up enough to force a "primary starter" (ala Eifert, Rudolph, Niklas, etc.)?
2. Will 2 TE's step up enough to make the 2-TE formation our primary formation again?
3. Will there be a heavy usage of situational TEs (receiving TE flexed out, bigger TE kept inline, etc.)
OL
1. Who will win the battle at Center?
2. Who will win the Tackle position opposite McGlinchey?
3. How health can Alex Bars get?
4. Will any of the younger OLs force their way into the rotation, or will it be more senior players?
5. How quickly can we find the lineup for this unit?
6. How well can this unit congeal before the Texas game?
And that's just the "high level" questions on offense......
