No. 1: SF 49ers defense didn’t make proper adjustments

We all know by now cornerback Brian Allen was used by the SF 49ers to disastrous results, a result of the fact that the team is just so thin at cornerback.

And let’s make no mistake about it. He was really bad.

But as Niner Noise has already pointed out, this is on defensive coordinator Robert Saleh and not on Allen himself.

Allen was outmatched, but it wasn’t his fault. He’s a practice squad player who got on the field due to necessity and wasn’t given any help from the first play up to when he was benched.

A scapegoat, if you will.

He didn’t have safety help, and the rest of the defense was powerless to do anything as Allen got picked on by the Dolphins as they racked up touchdown after touchdown.

Saleh has been a good coach at times, but his absolute inability to stop scrambling quarterbacks is of concern. The Dolphins’ Ryan Fitzpatrick is hardly a great scrambler, but he was able to find space and extend drives like almost every other quarterback before him this season.

Saleh got outcoached, and it just isn’t good enough.
