I can guarantee you that my opinion on Chaisson has nothing to do with groupthink or highlight videos.
I watched literally every snap Chaisson played against Georgia, Oklahoma, Florida, Alabama and Clemson. Every snap of Henderson's against FSU, Georgia, Auburn and LSU.
And it wasn't even these 7 minute cut-up videos on YouTube, the entire games are on there and I went through each of them, except for I think FSU where there was only a condensed version. It's not All-22 unfortunately but for OL/DL you aren't missing too much, and for Henderson I couldn't watch him all the way throughout every single snap but I for damn sure could see the multiple times he got roasted for 40+ yard receptions, including an All-22 view where you can discern the overall coverage.
I can also tell you that that scouts often times don't watch every single game of a prospect, it usually is a sampling of about 5 or so, spread out throughout the season so you aren't watching just games from the beginning/middle/end of the year.
I just got around to watching them seriously now because it's looking like they're the top two options at 17, and of course scouting isn't my job so I don't have basically my entire life to devote to breaking down film.
