Maybe. But if you look beyond the FG, you see that the inability to close out the Philly and Atlanta game were more or less examples of the fatal flaws in this roster. We didn't have the OL to protect Carr well enough for him to get into FG range or score a touch down in the last minute against Philly and we didn't have the pass rush to stop Philly or Atlanta on their final drives. Although I guess to be fair, the final Philly drive was more about our DBs running into each other than lack of pass rush since we were playing to contain Hurts.
Would Adams make the difference in those two games? Maybe, but I don't think it's clear that he would.
