Here is what I expect to happen come draft day:
Scenario 1 - We trade up with the Broncos and take Jaycee Horn over Surtain. The Cowboys end up with Surtain and he goes on to have an All-Pro career while Horn has a career similar to Morris Claiborne (sticking with the Cowboys theme).
Scenario 2 - We stay at 12 and draft none other then EDGE #1 Kwity Paye over Jaelen Phillips. Phillips ends up going two picks later to the Vikings. Paye matches his non-existent production in college and is bounced around the league and Phillips goes on to be a multi time pro bowl player, racking up 10+
