I watched that game a few times on NFL.com's all 22 and Holloman was a big reason why we lost that game. There were a few runs by McCoy that either kept drives alive then eventually scored or were for big gains. Holloman couldn't fill the hole because he either took a false step and was locked up or he took a second too long to diagnose the play and couldn't get back. He has some promise but I wouldn't count on him as being starter material next season unless he drastically improves.
OK, I watched all of Holloman's plays in the 1st half and watched him on all run plays in the 2nd half.
There were 3 run plays that where his play was questionable, but it was not an obvious mistake by him.
1. 2nd and 10. Run up the middle. Both DTs are getting blown back. Holloman commits early to the right side. McCoy goes to the left side of the DTs for 3 yards. I appears that McCoy gets 3 yards regardless of which side Holloman takes based other players being blocked out.
2. 1st and 10. Run up the middle. Hatcher was double-teamed and pushed back. Holloman had to commit to one side of Hatcher because McCoy had an opening on either side. I think that Holloman made the correct decision. It appears that the combination of the 1-tech and Carter were responsible for the other side. The 1-tech (#70) got blown out and Carter was tied up on a block. McCoy runs to the opposite side of Hatcher from Holloman for 20 yards.
3. 2nd and 19 after a sack by Holloman. Run up the middle. Hatcher is double-teamed. Holloman commits to the right of Hatcher because there is nobody else to cover that gap with only the DE with outside contain. McCoy goes to the left of Hatcher for 16 yards. The 1-tech DT is single blocked but gets driven out of the area. Carter is there but can’t get off of a block.
Summary: You could question Holloman on the 3 plays above, but I believe that he made the correct move on all of them. The DTs getting pushed back forces him to commit to one side sooner than he would if they could hold their ground.
He was much better than I remembered, especially considering that he was rookie late round pick that was a Safety/OLB in college and was forced into action at MLB.
