I don't know if guard is that much more difficult than tackle. I thought Noteboom had a future at tackle. He's talented enough to think he could play other positions. But his play at left guard left something to be desired. Still, the kid has too much talent to give up on. I agree he should wait longer and completely heal himself. If they can get him right, all that does is make the line that much deeper. I really believe guys like Edwards, Evans and Corbett are good enough to start. With a healthy Noteboom in the mix I think they will be much better prepared for the inevitable injuries.
Trying to keep it short as possible here snackdaddy & this being just my opinion on your first sentence....yes both all the five Ol positions require much of the same skills & abilities with requirements varying in all five too.
Noteboom does possess most all the needed skills to play the LT/RT posts &
even LG post in the right conditions but that LG post demanded more from Noteboom of several skills that he is in short supply of & just does not have....simple as that. Plus if he had be playing between John Sullivan & Whitworth @ LG instead of Brian Allen those first 6 games might have been a total different story.
He's got excellent needed wingspan, fluidity to mirror, outstanding launch velocity & acceleration but has
shown little power & zero combat skills that an interior Ol would need to prevent him from being the perfect LG to be
victimized by the normal nasty mean large strong DT's he would match up against each week. Kromer should have known this!
