I don't get the angst about Spriggs. It's not like he's all potential and wasn't that good in college.

Spriggs excelled in his senior season, catching second-team All-Big Ten accolades along with the eyes of scouts. The four-year starter also was named first team All-American by the Football Writers Association of America and third-team honors by the Associated Press. Spriggs had a scary moment on the field in 2014 against Michigan State, as he was taken to the hospital after suffering a helmet-to-helmet blow. But since them he has shown the build (6-foot-7, 307 pounds), anchor in pass protection and willingness to block through the whistle to be the type of prospect NFL offensive line coaches will covet at left tackle.

A former tight end, Spriggs was a four-year starter at left tackle for the Hoosiers and showed steady development each season, filling out his frame and holding his own against the Big Ten's top rushers like Joey Bosa and Shilique Calhoun.
He was named second team All-Big Ten in 2015 by the coaches and media and one of six semifinalists for the Outland Trophy. Spriggs was charged with only two sacks allowed in 431 called pass attempts.

In 10 starts in 2014, he allowed just two sacks and was a consistent force in the run game, helping Tevin Coleman rush for over 2,000 yards. Spriggs did not redshirt and missed only one game for the Hoosiers because of injury.
