The Rams, collectively, just don't have the 49ers' heart. The "Boys from 'Da Bay" like to tussle and I don't think the Rams, to a man, feel the same way.

In the end, it comes down to desire and effort. Three players on the Rams' defense had that 49ers runner stopped 5 feet from the line to gain on 4th down and the 49ers player outmuscled them.

It comes down to heart.
