Did Colin Kaepernick just do the practice demonstration as a platform to keep him in the news?

Colin Kaepernick recently was given an opportunity to do a practice in front of any and all NFL teams that wanted to observe. This was for Saturday, 11/16/19, at 3 p.m. Something like 28 of the 32 teams had committed to having someone there to watch. It was scheduled to be conducted in the Atlanta Falcons stadium with their video equipment all set up so teams that couldn’t attend could still get good video. At 2:30 p.m., Kaepernick just randomly decided to move the tryout to a high school field 60 miles away. This seems to be extremely odd for someone that claims to want to be taken seriously as a contender for an NFL QB position. Did he make this change just to show he could? Is he trying to build another case for collusion against him since only 8 teams made the move with him?
