http://draftbreakdown.com/ - There's the prospect videos. You can find all their positives and all their negatives. Don't know Black though.
As for Savage, I don't hate him. I'm fine with him coming in and competing with a vet and an early round pick to start the season. To compare Goff or Wentz to Savage, he's behind them (at least as far as coming out of school, no idea right now as he hasn't taken many meaningful snaps) in terms of accuracy, pocket awareness, finding and anticipating tighter windows, and well behind Wentz in overall athleticism. Savage has a big arm, will hang in the pocket, continues to grind, but the negatives are there when you watch him in actual games. Maybe those negatives have been improved on, like I said I'd be interested to give him a fair shot to prove so. But I wouldn't feel comfortable whatsoever going into the season just assuming so and counting on him to up and be
the guy. If you would, ok fair enough, but I don't get coming to that conclusion on some old highlight videos.
