Can I make a recommendation? And this goes to everyone that post videos of players they like. I'm not just picking on you. Please take this constructively.
Do not post highlight videos. They don't do anyone any good. Don't watch them. They can drastically skew your evaluation of a player.
There is a website, Draft Breakdown here:

That has cut-ups of LOTS of games for these players. Every play. Every down. Watching a player fight through 50+ "normal" plays is really how you evaluate talent, not just his peaks.
You have interest in Andrew Billings? Here are seven games from the last two years to watch:

When you watch THREE of those, tell me what you think. And the key to evaluation is elimination. Tell me why he WON'T fit first. What does he have to improve on? Are they fixable? What's his effort like? Is he winning on talent or hard work? Look at his feet. Look at his balance. How many times is he on the ground in a game? What's his most comfortable "roll" in Baylor's defense? Is the defense and players around him helping him or hurting him?
