see i just hate having certain formations...plus with certain playbooks there is too much on one certain play...dont need three different cover 1's that all execute the same way..the same could be said for other plays as well...
on a side note...if I shift the line..i not a fan of the line still trying to follow there assignment drawn up in the play...ex. if the line is to rush straight ahead...and i spread the line to have the ends line up off the tackles outside shoulder...they will rush their original assignment and make there first move to the inside shoulder...i have found by re-assigning the ends or OLB to rush straight ahead helps combat this but can be to much at times...
