How do you know? Dex seems like a well meaning kid just makes bad decisions. I’ve heard he works very hard and loves to compete but loses focus at times. That’s enough to work with as a college coacheasy answer. dex is not interested in being coached. he has talent but is a dog.how come other backs have not had a problem pass blocking ? denson is not an elite coach but the problems with dex are 100% with the guy in dexters mirror.
