What's the main cause of the defense's fourth-quarter failures?

Bad coaching decisions were the reason for 3 of the 4 losses. Unless those decisions get better, we'll continue to see losses that are avoidable as long as Riley is here. If you don't believe me, you better keep in mind that his previous team had losing records 3 out of the last 5 seasons.

Coaching

Same set of DBs had very good stats last year. Yes, losing RG hurt, but the secondary didn't look inept last year.

Old habits may be hard to break from prev system...and under pressure the confidence wanes and confusion sets in

Coaches don't know how to close out a win!

Because wins build confidence and we need wins! Losing is NOT an option. Losing is NOT acceptable!

Coaching, coaching, coaching. We have the same or better talent, the same or better physical training and facilities. What remains? COACHING. TIMID COACHING.

Somebody's not making the best decisions.

Confidant in the players..but being on the field so,so,so long even the most physically endurance athletes would be wore out..

If you can't put pressure on the QB and give him all day in the pocket he will pick your corners apart I don't care who you are playing. It would also be nice to see our DBs turn around once in awhile.
