At a glance:
I'm not seeing a big change but the team I was playing had GL defenses in:
HB Sweep vs B Gaps Fire: 54 yd TD untouched
http://glb2.warriorgeneral.com/game/replay/66062/1098895QB roll out vs GL Gap A: 80 yd TD - there was a missed diving tackle on my QB
http://glb2.warriorgeneral.com/game/replay/66062/1099989HB Sweep Strong vs B Gaps Fire - 58 yards before touch
http://glb2.warriorgeneral.com/game/replay/66062/1100233HB Sweep Strong vs B Gaps Fire - 1 yard gain
http://glb2.warriorgeneral.com/game/replay/66062/1100715GL Sweep vs GL Gap A - 24 yard gain
http://glb2.warriorgeneral.com/game/replay/66062/1100808Sweep vs B Gaps Fire - 34 yard TD
http://glb2.warriorgeneral.com/game/replay/66062/1100863QB roll out vs GL Gap A - untouched 80 yd TD
http://glb2.warriorgeneral.com/game/replay/66062/1101344Sweep vs B Gaps Fire - 68 yd TD
http://glb2.warriorgeneral.com/game/replay/66062/1101758Sweep vs GL LB Contain C - 69 yd TD
http://glb2.warriorgeneral.com/game/replay/66062/1101972QB Rollout Strong vs GL Gap A - 43 yd TD
http://glb2.warriorgeneral.com/game/replay/66062/1102260Sweep vs B Gaps Fire - 21 yd
http://glb2.warriorgeneral.com/game/replay/66062/1103029That is every time I ran it in my scrim this morning vs Lincoln (sorry - don't know if it is private or not). So - I'm hoping that some of the non "gaps fire" defenses do show an improved AI.
Lincoln only ran it once that I remember:
HB Sweep Strong vs Man Base 5-2 and the D did look improved:
http://glb2.warriorgeneral.com/game/replay/66062/1098947Sweep vs Zero LB Dogs looks roughly like it did before (to my perception) - 10 yard gain...but that included a broken tackle and a drag
http://glb2.warriorgeneral.com/game/replay/66062/1101468That was every GL roll out / GL sweep from my game this morning - please post yours - but it wouldn't appear that there was any kind of drastic nerf hammer lowered here.
(I'm not sure about outside blocking - it kind of seemed like blocks might be slightly harder to engage 'from the side' than they previously were...but I didn't see enough to tell for sure)
