He will be tried at corner. That position is simply too valuable so you have to look at it first. NFL teams won't care about his college specifics. That 32 3/8 arm length is a prized commodity at cornerback. More and more teams are recognizing it. That alone will probably lead to Redwine being drafted higher than currently projected.
The Seahawks have made a living out of unheralded long armed defensive backs who test well. They have not drafted a cornerback with sub-32 inch arms in the Carroll/Schneider era.
And there'a a very good reason for that...every multiple first team All-Pro cornerback drafted since 1998 has had 32+ inch arms.
The Dolphins would be moronic to make Xavien Howard one of the highest paid cornerbacks in the league, given his subpar 31 1/4 arm length. The league average is 31.5. But the Dolphins tend to overlook analytics, etc., in favor of grinding out via flawed subjectivity. Perhaps the new regime will be more astute.
