With the increase and proliferation of spread offenses today. Packages are on the field more of a game than the oldschool standard sets. That means a greater need for 'specialy' types of players that fill in either as linebackers or safeties in function. Once one starts to transform a positional identification, what does that player now get paid as? Linebacker, or safety? Also, that demand will being into view more players with dual abilities that are apparent. Allowing just such a player to come up to the line of scrimmage and function as a linebacker...then drop back into over the top roles. Dallas has picked up on this specialty type of player somewhat, with the draft selection of a Darren Woodson type linebacker, Will Smith. This requirement, also could affect types of cornerbacks that are acquired in the future as well. A rather large corner, can spend his first five years in coverage as a cornerback, and when speed starts to slow slightly, can then bump up to linebacker or back to a safety role. But problems of salary has to take a directional turn, starting now, as teams learn to handle those changing roles.
