nah man, for me you've got to watch non-highlights especially with safeties
Cisco's probably the best example this year - if you watched his highlights, you'd think he was the 2nd coming of Ed Reed on steroids... an absolute boat-load of picks, jumping underneath routes to make highlight-worthy hits or break ups
from his highlights you'd probably think he has great anticipation, great physical tackler, erases the middle of the field etc.
but in actuality he's a free-lancer who blew a ton of coverages, is an inconsistent tackler - and generally a really inconsistent player on a drive-by-drive basis
with corners i like to be able to see what they do when they get beat, or what they do when the ball's not coming their way (not gonna learn a ton about Caleb Farley from his highlights because in his 2 best games they through to his side of the field maybe once or twice and that was it...)
but they're probably the 2 hardest positions to scout as a lay-person because of the lack of access to all-22 but it's worse for safeties because they rarely appear in replays on good plays either lol unless they made a play in man coverage
