Geoff, always a pleasure to read your well-considered and spirited answers. My question is about tight ends. Given the monster performance of our own Tyler Eifert on Sunday, and the performance by other tight ends in the league (most notably Gronk), is the role of this position permanently changing, becoming more central in a game plan? Are the coverage mismatches these big, fast men create going to change the way defenses prepare each week? Or are these receiving tight ends just a fad, like the read-option QBs of just a couple years ago? Thanks for your time.
