NFL teams blitzing in preseason?

[WayAbvPar]

This seems like a relatively new development. Since offensive teams don't scheme for particular defenses, this seems like it would give the defense the upper hand and really endanger the QB. This leads to teams not playing their #1s much at all, which in turn even further dilutes the product. Not terribly fair to the season ticket holders, who get raped for full price for 2 exhibition games per year (adding ~50% to the price).

Thoughts?
