It would be nice to have Martz back in the game and to see if he's tweaked his offense to ensure better pass protection.
Well . . . there are only a few ways to improve pass protection. Either the 5 guys need to do a better job or the QB has to get ball out quicker . .. both of those are on the players. The other thing you can do is keep a back or TE in to pass protect which takes away one of your eligible recievers. If you want a wide-open 5 receiver offense you have to protect with 5. If you want to protect your QB you need to keep at least 6 blockers and that reduces your receivers to 4.
If you run 5-man protectuions, your QB is going to get hit, but if you can withstand it, and your skills players are good, you get the GSOT. But that comes with a cost.
Warner, from 1999-2001 got sacked 6% of the time. From 2002-2006 he got sacked 8.5% of the time, and that's with 3 teams. He simply held the ball too long. From 2007-2009 he go sacked 4.4% of the time, Coach Whiz talked about how he got ball out quicker and the "old" Kurt Warner was back.
So, yeah, if your 5 OLmen are not up to snuff, the GSOT does not work. If your 5-olmen cannot get it done, you need 6-man protection. Will Martz change? No idea.
