Here's a video of the Colts' top pick, Sanders:

My first impression was pretty good, but when I watched it the second time around I have more doubts about how his game will translate to the NFL. If you notice throughout the video he doesn't wrap-up tackle, instead he propels himself headfirst into guys, which makes it a bit hit or miss--something you don't want in a safety. I also noticed that he bounces off guys (even a QB) without bringing them down, this is all the tape I've seen so maybe I'm wrong, but I think in a Andre Johnson (6-2 220) v. Bob Sanders (5-8 200) collision in the middle of the field that Andre may get the best of it.
