lets talk collective bargaining

So, let's be honest here and acknowledge the CBA.  By rule, there are so many padded practices.... so many opportunities per week to work on true schemes.  If you are a team with a starting qb in the vein of Palmer, can you afford to look at Manziel as an option?!!?  How will he get time to work with the o in the same scheme as the typical o you are running week in and week out.
