It's understandable for fans to want so badly for Alex Smith to succeed that they convince themselves that it's likely to happen. It's comforting to think that an overall #1 pick wasn't wasted, along with the millions of dollars.
The concept of a sunk cost is appropriate here. The fact that millions have been already wasted on Alex Smith is irrelevant. What's done is done. THAT MONEY HAS BEEN WASTED. The relevant question is this: will Alex Smith continue to be a waste of resources, or will he be the best option going forward?
I've seen nothing . . . aside from maybe that one Seahawks game or that one Cardinals game . . . to show that Alex Smith should be a starting QB in the NFL. He's garbage.
