Did you even watch the game???
Henry had 36 carries for 158 yards. By any reasonable standard, they DID keep "feeding him the ball."
If you take away Henry's one breakaway TD of 50 yards, the rest of his carries amounted to 35 carries for 108 yards, which is 3.1 yards per carry. Three of those in a row doesn't average a first down, a team can't sustain a drive with that kind of average. And by the second half, instead of the defense withering under Henry's power, there were lots of times when he got hit and had no push, just got pushed back or went down quickly. Clemson did an OUTSTANDING job of containing a superb back.
I hate Kiffie as much as anybody, but his calls for passes to the TE were what kept Bama in the game, and those plays were well-timed, well-designed, and well-executed.
