re: Hide the offense or use every opportunity to work on it openly?

Running base plays is not hiding your offense. Every offense has their base plays that you have to perfect and then the rest of it is built around those plays. You really think not running every play in the playbook on one day in April is going affect how the offense develops? They run every other play the other 364 days out the year.

Fans just need to admit thy are mad to hear the offense is going to be vanilla because they selfishly want to see every play. He coaches have seen these guys run those plays and will see them run them 100+ times between now and kickoff.
