Not bad overall, but I don't think you'll find many people here who are very supportive of keeping Jonas under any circumstance. I think most people here believe he is too injury-prone, and even with that tag he will still probably get offered more money on the FA market than he's worth. We seem to end up playing Price quite a bit as it is, so why not just keep Price in there?
I think it will really depend on how the coaching staff feels about McFarland. If he is ready to be a productive backup next year, then we may see Jennings leave, and have Price as the starter backed up by McFarland. If McFarland is not ready, I'm not sure what will happen, because depth is everything in this sport, particularly on the offensive line.
A lot can happen between now and the end of the season, and Jennings' value on the FA market will likely change before then in some way. If there aren't many takers, we may see him back, but I'm not counting on it. If teams are willing to pay through the nose for above-average players -- and it seems they are -- then we're not likely to see him back.
