The "64% completion rate" for Martinez that gets used as an argument for how much better he will get just doesn't hold water for me.
Sure, he is gonna get better and improve. Yet, there are all kinds of working parts to an offense. For me, one cant say that he will improve from 64% to even better. It's not about that percentage increasing to me. He will get better, sure, but it won't or doesn't mean he goes up to 66%, then 70%, then 72%. This isn't realistic or fair.
I liken this to running a marathon or running a faster mile. As one who was trying to break the 04:00:00 mark, it's one thing to lower a pace for a mile. It's quite a other to sustain it over 26.2 miles with all the ups and downs of what you can control verses what you can't. Their is quite a lot of effort and conditions that go into improving a pace or percentage to make it a lower pace or higher percentage when you get that low or high.
All that go say ... I will be totally happy to see AM improve as a QB and hover around 60% completion rate while becoming smarter and a better leader in developing the team as a whole. Finally, he certainly has the potential to increase his completion percentage ... but his greatness isn't going to be measured by just this one factor.
