1) If Blue struggles in pass pro, they could do the 2019 LSU thing and just send out five receiving targets on obvious passing downs (LSU would motion CEH out to the field next to the sideline and either a LB would follow him or a CB would be sacrificed on him). Quinn would need to be better managing pressure for this to work though
2) Texas is so loaded at WR and probably TE that 11 and 12 should be more than enough to get you to an elite offense
3) Blue ideally is running outside zone types of plays (he's excellent there), but there's a chance he's still more than fine on IZ/Duo/Counter. He wasn't particularly good as an inside runner as a prospect, but watching the video posted earlier in this thread of his carries throughout the season, he got better at it as the season went on, especially as he got more reps with the first team. He's also a threat to hit a home run on an inside run if a LB misses his gap/gets blocked or bouncing it outside
