It actually doesn't tho. As a huge Manti supporter I hate to say it, all he did was prove he has average speed. Something people already knew, something the tape proved.
Only way his stock really has a chance to go up is through all the team interviews and meetings, and by all accounts, he's knocked a few of those out of the park, and homered most of them (don't mind the baseball terminology, just getting ready for the season!). In my opinion, his value is between 20-35, and his name will start coming up around #19 for the Giants.
Ultimately, I believe he will be the 25th overall pick. Minnesota loves ND players, they have a huge hole at MLB, and Speilman (GM for vikings) has had heavy praise for Te'o about who he's handling the media circuit, and met with him at the combine and was here at the pro day today.
Te'o will be a viking unless he goes before then.
