Yea, I don't either. You just don't know whats going to happen with other teams throughout the year. Look at what happened with the Titans, they selected Mariota in the 2015 season and still finished dead last. They knew they didn't need a Qb 1st overall in the 2016 draft so they traded out. It could very well happen that a team like the Bears finish dead last in the NFL, they just selected Trubisky, they could want to trade out of that spot. Or it could be another team in the top 5 or 10 picks that wants to trade out. 
  
There are just too many variables.
