This was stated a few years ago, but seems like it needs to be restated. You don't have GAME TAPE, you've never seen GAME TAPE, so please stop telling people to "go watch the tape" or "I like this player on tape." Now, I understand this does not apply to all of you, and I apologize for those who actually do have access to something most of us do not have access to, but by and large, this claim of "game tape" is absurd.
Now there are 4 types of tape that I know of:
Scouting Tape: This has every angle of a player, and follows the player, not the play, through every play they've been in. Trent Baalke and staff watch this. NFL Network crews have this. 99-100% of people here have never seen this.
Game Tape: This is recordings of the actual game. While this has limited use for certain positions (CBs--because if they play well, they won't show up on game footage), it does give you a strong sense of a player if you focus on them. While many have seen Andrew Luck on this type of tape, please don't tell me you've evaluated the likes of Stephen Hill. I may be a pessimist on the topic, but somehow I don't think many people recorded Georgia Tech games to watch in the offseason.
YouTube isolated plays: This is the best resource I know. It has several players (far from all), and shows every play they've participated in for a few games. Highlights, lowlights, and even blocking plays for WRs. This isn't perfect, but gives a good sense. If this is what you refer to watching, I can appreciate that. It's efficient and effective, and given that none of us are paid evaluators, it's pretty good for our purpose.
YouTube highlights: This is the lowest possible form of evaluation. It is a compilation of good plays a player has had, with slow motion, background music, and limited special effects. I can put together a highlight reel of ever NFL player, including Kwame Harris, JT O'Sullivan, and Mark Roman (OK, maybe not Mark Roman). If this is the "tape" you've watched, please be honest and say, "In his highlights, this player has not dropped passes" rather than "shows great hands on tape"
Again, my apologies if this does not apply to you, but there are some that I believe have been mis-using the term "tape" to imply something that is not accurate.
