Its not a side arm throw that is the problem.Concerning or nothing to worry about?
If he didn’t throw 2 picks I wouldn’t even bring it up but I do think this is a topic of discussion among fans.
1) Two of his three interceptions he has thrown very late across the width of the field - if there is one pass that is almost guaranteed to have a very high rate of interception it is those. The ball is in the air for a long time - no matter how strong the arm. He has a gun and just like all strong armed quarterbacks or fast running backs learn you can't out run everyone to the outside every time, he will learn - hopefully as the good ones do - that even for a howitzer armed QB, that is a bad throw to make.
2) The second was an admitted mental confusion / mistake between him and Noel. So it had nothing to do with his "side arm" throw
