Yea this doesn't seem like a deliberate example of running up the score. Kneeling is the respectable thing to do in those situations, but a lot of people still run the ball with under 2 minutes left even when the other team has no timeouts. I've done it myself and actually scored once I think (I wasn't proud of it and apologized later...don't remember who my opponent was)...but I don't think people do it with the intent of scoring. I don't think you'd expect that with under a minute left you're gonna break off a 50 yard TD run. In my opinion, running it with under 2 minutes left is okay under certain circumstances...but obviously not the epitome of respect. If you're in the red zone and running it with under 2 minutes left, that seems like a more deliberate attempt at running up the score, but when you're in your own territory...it doesn't seem like that was his intent. And if you do run it with under 2 minutes left, you should be killing as much clock as possible in between run plays. It's probably somewhat a mix of carelessness and boredom, cause running the ball for a few yards to kill the clock is a lot less dull than kneeling it.
siradam has been playing with us for a long time and has definitely been respectable so I don't think we need to call him out on something like this. I actually think we should commend him for almost breaking 100 yards rushing in a game...! But it looks like you guys had a good close game, so just put that one play aside and just get ready for the next week. And way to overwork your rookie WR in his first game red worm...he has to learn from the veterans first!
