Alex Smith
I like Shaun Hill but at the end of the day Alex is just more talented. I think Martz will bring out the best of Alex and hone his talents for the benefit of this team. When Alex turns it on, he can be pretty good. Again, Im not basing this off "blind love" or anything stupid like that. Im basing this on the fact that Alex DID improve under Norv Turner...and I just think that with a Qb/Offensive guru like Martz at the helm...Alex is MORE THAN LIKELY to improve further. Its just basic logic. Martz has turned people with limited talent into potential HOFers. I think Alex's talents have yet to be utilized. I think Shaun Hill has a lower ceiling if you will.
Alex has deep arm capability, decent accuracy (when healthy...58% in 2006), and decent running vision/ability/escapability.
So again, based on logic...
Alex = good WHEN he has a good offensive coordinator
Therefore under Martz/Tollner = I suspect Alex will be pretty good.
Either way..go 49ers.

In case you can't tell these are the arguments of haters and every one of them is wrong.
