The New England Patriots can't rely on their passing game alone.
That's one of the biggest takeaways from this season. Tom Brady and the Patriots passing game were good enough for long stretches, but without a running game to fall back on, the Patriots fell short.
Part of the problem was the run-blocking up front on the offensive line, but part of the problem was the depth at running back. Yes, the Patriots were plagued with multiple injuries at the position, but their problems running the ball began well before either Dion Lewis or LeGarrette Blount got injured.
So, while adding depth at running back won't solve all the issues, it's a good place to start. Here's a look at some of the available free-agent running backs the Patriots should be considering this offseason.
