Exactly what I was referring to. They very easily could of used both Jackson and Lucky in the backfield last year, especially on pass plays to get more play makers on the field. Using Castille as a fullback on some sets gives BC the option of motioning lucky out of the backfield for mismatches in the passing game and still leaves him with a running threat behind Keller.he showed no imagination when it came to putting 2 or 3 backs in the backfield....hell, i can't ever remember when Jackson, Glenn and Lucky were EVER on the field at the same time, not one godamn time.........EVER. guess that would have been stupid, eh? guess we will never know, eh?
