Some items of interest
» Kansas is the only school in one of the five major conferences (ACC, Big Ten, Big 12, Pac-12 and SEC) without a participant.
» More than half of the quarterbacks at the combine (10 of 19) are from the ACC and SEC (five each). There are zero quarterbacks from the Big Ten, Big 12 and Pac-12.
» Alabama, LSU and Florida have the most participants in the SEC, a combined 31. That number would be fifth-most among conferences.
» Florida State (nine) and North Carolina (seven) combined have one-third of the ACC's 48 participants.
» Ohio State and Wisconsin lead the Big Ten with six participants each. Having six participants would rank fifth in the SEC, third in the ACC and Pac-12 and tied for first in the Big 12.
» Baylor is the only Big 12 school with more than five participants and one of only three league schools with more than two.
» The Big Ten is a league long known for its line play. But the SEC has a combined 28 offensive and defensive linemen at the combine, while the Big Ten has just 10. There are just two defensive linemen from the Big Ten; the ACC's Boston College has two by itself.
