I think its great to promote safety, but it just seems stupid and unfair to protect one position over the others. All that it does is destroy parity and help the teams that have marquee QB's. In general, parity sells tickets for all 32 teams. Dominating "evil empires" just sells tickets for 3-4 teams. If it was expected that your QB could miss time due to injuries that any position sustains, it would force teams to invest in back-ups, and you would see the top QB teams having to limp into the play-offs with 10-6 records for often with their golden missing 3-4 games at a time. I don't see the fun in letting some teams win the lottery at QB, and giving them 13-3 seasons for 15 years in a row.
