Instead of wasting draft picks to convert Jim Schwartz's perfectly good 4-3 defense into Rex's bumbling variation of his father's 3-4 defense, he could have kept the defense intact (keeping Schwartz, whose defense in Philly went on to beat Brady in the Super Bowl), been a head coach instead of a glorified DC, and drafted a QB or two. Rex wanted Tyrod and he ignored the offense so he could run his defense with his guys.
