Not a Simpson or McShay fan and stopped being a draft fan over a decade ago . . .
Anyhow, if I got this right, on this play we got Alabama's best receiver, Germie Bernard, projected as a RD1-2 pick, locked in press man coverage against safety Ashlynd Barker. He shows press man at pre-snap. This game is Barker's first start. He's 6'3" and not one of these quick, shifty safeties. The year before, on FSU's 2-10 team, Barker tallied a grand total of zero passes defensed.
McShay talks about Simpson's full-field progression, but I'm not sure how much reading he should be doing here. (I don't know.) From the safety of my comfy chair, this looks like it should be the football version of a gimme or a layup - no pass-coverage safety v. NFL caliber, #1 receiver.
McShay pulls one play out of a game where Simpson had a 53.5% completion rate and his team lost 31-17. I just don't know if that one play is actually representative of anything.
