I think these things...
I think Fisher is aware of his limitations when it comes to O matters.
I believe that explains his tendency in the past to rely so heavily on both Bradford and Schotty. Both let him down for various reasons.
I believe Fisher is a big fan of Foles and is still pinching himself because he can't believe his good fortune with the Kelly trade offer. Yet he picked Mannion in the 3rd round, didn't he? No more getting caught with all his eggs in the same basket, QB wise. Lesson learned.
I believe Fisher chose Cigs because he felt that Cigs would produce a solid, efficient, and very effective O for the Rams this year. One that can compete in the NFC West. I doubt that Fisher was ever seriously comfortable with some of the more flamboyant OC candidates, and the feeling was probably mutual. Lol. Point is that Fisher chose Cigs with great care after weeks of consideration. The last thing Fisher wants to have to do is micro manage his OC.
I believe Fisher selected his QB coach with great care. I believe this one may be his most underestimated offseason decision, actually. He took his sweet time in the process because of the importance he attached to the coaching position, given his own limitations in that area. I think he might have struck pay dirt with Weinke.
Hopefully, all of the above will result in a playoff worthy O to complement our current playoff worthy D and ST.
