I talked about this on last night's show.
This 'can't throw to the right' report comes from John Clayton, Matt Williamson, and Bill Williamson. Clayton and I discussed it when he was out at Dove Valley a couple of weeks ago.
On a 9 route (go) Manning can put proper air under it, and can even throw with zip to the right or anywhere on the field. His 'window' throws (in front of Safety, over Linebacker) to that side don't look as good as the one's to the left. He's made these throws (and plenty of them) in practice.
In games he needs to get used to the speed again because his flutter passes come right, left, or middle. The reason they happen is when he tries to put a little extra spin on it. Any delay in a read or decision that is *just* a little late requires some extra emphasis from his arm and that type of window throw has resulted in some bobble throws.
He doesn't have a young man's arm. There has been no debate over that. I still think he's going to be more than fine when the rust has shaken off. The Broncos could start the season with a rough month of September, after that I expect them to find their groove.
Bottom line, he's not Chad Pennington and 'can't throw to the right' talk is seriously, SERIOUSLY, overblown. Clayton didn't overstate it in his report, it was just his observation from one day at camp. Manning's preseason has not looked as sharp as his practices, and that's on throws everywhere (especially to the middle).
