I don't see a lot of downside in letting Jake go right now. We can get similar performance for a lot less money next year.

Here's an intriguing longshot - move Martin to LT (and hope he plays better there), and look at someone like Jovan Olafioye (from the CFL BC Lions) as a potential RT replacement. 6-6, 325, long arms, good feet/athleticism. Raw but very teachable, and probably pretty cheap. Something to consider...
