So, I was doing some poking around looking at some stats of freshmen in the Big Ten. And Shields rebounding numbers stuck out to me. He had 133 boards, which by itself puts him fourth in the conference for freshmen. But, consider that he missed five of the first six this season and think where he could be!
After the Oregon game, where he only had 2 rebounds, he had no fewer than 3 the rest of the way, averaging 5.86/gm after that game in Eugene. Even with the outlier of 13 vs. Michigan St, he averaged 5.5/gm. If he had been able to play all season at that pace, he would have had been in the 170 rebound range for the season. If you include the MSU game, it jumps to 180 ish. That'd put him right around Deshaun Thomas and Glenn Robinson III on the conference charts, not just freshmen.
I know you can't cleanly extrapolate stats like that, but consider what he did in the last 22 games of the season is pretty impressive. I'm not sure how that compares with other PF's in Husker history, but it rates fairly favorably with other big men of the past 15ish years.
As freshmen go in Husker history:
Maric - 169/6.3 (27 gms)
Turek - 162/6.2 (26)
Hamilton - 161/5 (32)
I'm sure I should include some others on this list...
