How do you evaluate prospects?

[panther4life]

I used to read media generated scouting reports and look at consensus rankings to determine who was worth my time. 

Then draftbreakdown.com, used to have a nice library of top prospects full games, condensed into 3-6 minute videos showing their every snap. Now that option is gone and I have a tough time forming my own opinions of players. 
 

With all the extra free time I’d like to get into the draft again but need help finding resources.  Please point me in the right direction for my research please.

Largely based on guys I've actually watched play which is pretty much all of the prospects from major power five teams. The guys coming out of lower level schools, I usually just don't form much of an opinion on them because I have zero exposure to them.
