This has been an issue in recent Maddens (although it sometimes got patched later). It has to do with how much the replays are compressed, I think. Basically, it's a developer tradeoff decision between the level of detail in the replays and the replay length. It seems like EA went for the former choice for this game because while they are a bit short, the replays look really good.
That probably shouldn't happen though even if they went the detail route....I've seen kickoff replays and such get cut short, but nothing like 2 seconds.
