Apparently Duvernay met (informally) with the Houston Texans. He's also reportedly met with the:
San Francisco 49ers
New York Giants
Houston Texans
New England Patriots (Prior to NFL Combine)
I assume those are also informal meetings. NFL teams can meet informally with any of the players at the combine. However, they are limited to 45 of the formal, 15 minute meetings. I'm not sure of the timeline for those or who Duvernay will meet with in that setting.
