I'm beginning to think that you don't understand offensive football very well.
When you have a back who is doing that well, you feed him...when you give him only 8 carries in a game (2 in the second half) you have failed as a coach and YOU shut down the running game, not the opponent.
19 runs for 93 yards in first half..4.9 avg [Estime had 6 of the 19 runs for 32%...should have been even more]
8 runs for 11 yards in second half..1.4 avg [Estime had 2 of the 8 runs for 25%]
19 for 93 at 4.9 is enough in a half to get it done against Navy...8 for 11 is not.
You seem so stuck on trying to believe that I think we were going to roll the ball out, run every down for 8-9 yds a pop and never pass and that I think we were having great success running at will vs Navy, that you aren't seeing reality.
19 for 93 at 4.9 in a half, IS succes vs a good run defense! I'll take that all day...I would have liked to see it be more like 26 for 128, but 19 for 93 is enough.
The point is, Navy didn't shut that down, our coach(es) did. "We" reduced our rush attempts by over 50% in the second half (fact) and "We" reduced the run distribution from our most successful back of the first half (fact), instead of increasing it as a good offensive minded coach would do.
Navy has a good run defense, this is true...but they are not the reason our run game disappeared in the second half, Rees is!
