I really hate to bring this up because I think it's WAY premature, and could turn this thread into something I hate, but here goes (fingers crossed for good discussion)...
In the context of Tommy's impressive live debut, and presuming that Taylor doesn't get healthy in the next few weeks, it's likely that Armstrong will get several starts this year. All due respect to Ron Kellogg III, who looked equally impressive out there against SDSU, but he is not the future. Were he a Junior I'd write this completely different, but since he isn't and we have next year to worry about, the focus has to be on Armstrong now.
So in the context of a competent -and hopefully winning- Armstrong, when Taylor does get healthy, what do you do with him?
Several things to consider at this point:
With the defensive struggles we have, accomplishing anything of importance this year is unlikely at best
Next year's schedule looks quite similar to this year's, and with a year under their belt the defense should be better. Therefore winning a conference championship would be a more realistic goal.
Experience this year can only help make 2014 Tommy Armstrong better. See above for why this is important.
Taylor has a life after 2013 ends. If that life is to include the NFL, he will not be playing Quarterback. Taylor is no Eric Crouch, and Crouch couldn't make it in the NFL as a QB. Taylor's best shot at playing professionally is at another position.
Taylor is too good of an athlete to leave off the field.
If Armstrong is proving to be equal to the task, I say he goes from here on out at QB, and we take our lumps starting a Redshirt Freshman. Again. It likely means four losses again, but who cares? The experience is more valuable than wins right now.
Martinez should be a return specialist. On kick or punt returns he could be a game-changer. Putting him out there would also get Kenny Bell off the field at that position. It's a position he could pick up in a week's practice, he wouldn't have to learn an entirely new position like receiver (and he likely wouldn't see the field at wideout anyway), and there's no way we could put enough muscle on him to make him into a corner or safety by year's end.
