Did they? I'll go back and re-watch, but I'm pretty sure they wasted at least 30 seconds huddling up for 3rd and 4. Threw it out of bounds, then sent out the kicker with a timeout in their pocket.
That's inexcusable before you mention they wasted a timeout on defense immediately after the 2 min warning and immediately before giving up the big play to Landry.
I guess I'm not as upset about wasting seemingly critical timeouts on defense if they're not even going to use them.
Edit: Just watched again. I see what you mean. But, the timeout didn't even stop the clock, much like the first one used after the two minute warning. Very poor management.
