The main point is that the practices are waaaaay more important to the scouts than the games. The games are simply the reason that all these athletes came together to have these practices. If the game was so important why do players - every year - attend all these practices and then opt out of the game? If the game is so important then why do the scouts leave at the end pf the practices and not stay for the games?
I'm the one who brought up the topic of opt-outs in this thread. I already answered the 2 questions you asked. The players who opted out likely did so because they believed they did enough during practices that playing in the game would not have improved their draft stock. And scouts don't need to be there because the game was going to be broadcast on TV.
But having said that, I said those things based on Dublinirish's assertion that
most scouts leave town. Most doesn't mean all and it's extremely likely that at least some scouts stick around which means they aren't sticking around to
not care about how the players play in the game. They were still scouting and evaluating. And the ones who weren't there were doing the same from their offices on their TVs.
Also, I said
several of the top players opted out. I didn't say all. Andre Carter (DE, Army) was a borderline 1st rounder on most draft boards heading into the week. He struggled a bit in practices so he played. Tyjae Spears was a top-10 RB prospect who had a very good week of practice and he still played. And why would they have done that if the scouts didn't care and weren't even there? Why would any of the players have played and risked injury?
Because the scouts did care and they were watching.
