I agree completely. We as fans have been watching the oline decline every year since 2008. 2006-2007 Addai rushed for 1000+ each year.
After that is where it gets interesting. If I'm not mistaken, Gore has been our first 1000 yard rusher since then. You're talking about almost 10 years without a 1000 yard rusher. And in the same time span, i think there has been around 4, 100 yard rushing games.
When you cant run block you become predictable. Stop us from passing the ball and you slow the Colts way down. I understand why everyone wants a running back early every single draft. Having a rush attack makes things run silky smooth, and you can control time of possession easier. I just don't see why we have to get a running back before we get an oline. Let's say your top RB gets injured? No other guy is going to make things happen behind our line. Upgrade the line, you upgrade the running game, which means you upgrade the entire team.
So it's really just a debate between RB and Team. Do you want a better team? Or a better RB?
