Jon Nyatawa was on Benning & Sharpe this morning, and he made some good points about TM and TA. Now, TA may be the future, but TM will probably be needed if NU is to win tough games in November. Think about last year, when TM was such a difference-maker in wins against Michigan State, Northwestern, and Penn State.
Of course, Martinez is only effective if he is 100% and a threat as a running QB. Armstrong may not be the "breakaway threat" that TM is, but he could be the "steadier QB" of the two. Armstrong will get the 3-7 yards on his QB runs, and keep the offense on schedule. I am very interested in seeing how the offense responds this week (and possibly next week) under Armstrong, but it is way too early to be calling for TM to be benched for the rest of the year.
