I really don't know at this point. If it's me, he limped thru the spring recovering from a broken foot, and it's not surprising the stress he put on his other foot resulted in a break 2 months later. If it's me, you just let the kid heal and learn the position this year. He had a bone break senior year in high school, bone break freshman year at Nebraska, another break, and then this recent one. Even if he recovers in a month, that takes you to less than 30 days to fall practice. He's a competitor that won't want to sit out, but at some point, he does you no good on the sidelines.
It's what i've talked about with S&C (tho I wouldn't get too mad at our S&C for this). Injury prevention needs to be priority #1 for any staff. You get a limited amount of scholarships, and kids can't develop if they sit out all the time. I did make reference earlier in the year to someone putting on 40-50 pounds in a year not being good for their body as your soft tissue and bones can rarely handle it, but he's had these issues before. He also basically had to eat like a bird to stay at TE weight. When he was recruited, I stated he didn't have the hands to play there and needed to be an OLB or blocking TE. I'm a little surprised we didn't try him at OLB before making a major move to center, but I get it.
