Jared Veldheer

Saved the most obvious for last. To say Veldheer has struggled at right tackle so far this season is a major understatement.

While he was only credited with giving up two of the six sacks on Monday night, he has left Palmer scrambling often. Veldheer has done great things over the first couple of seasons in Arizona but has done nothing this season to resemble that.

Remember, he left during training camp. His teammates thought he was gone for good. He came back. Some believe he only came back for the money.

Whatever his motivation was to return, he needs to start earning that paycheck. He is hurting himself and his team with his performance.

He may be past the point of returning to his past glory at left tackle but he is still one of 53 men on this roster being counted on. Plain and simple he needs to be better. Not even at Pro Bowl level, just better. Enough to give Palmer more time to rid of the ball.
