That's kinda crappy to throw the ST coach under the bus. Chryst is the HC. HE should have been communicating to everyone that they were gonna go for it on 4th down before it got to that point. If the wrong unit was on the field, that's on Chryst. Even if it's not on Chryst, it is, because he's the HC, and everything runs through him. He's the one that ultimately makes those decisions, and at that point in the game, he knew before 3rd down (or should have) that he was going to go for it on 4th down, or have had a "will we or won't we" set of scenarios ready to go for 4th down on whether or not they would punt. Communicate, communicate, communicate. Throwing the ST guy under the bus is crap leadership.
