That's the problem isn't it? It's easy to have Kahne out but who's in? Byron isn't ready yet, so you have to look at the free agents. The list is pretty appealing, but what does that mean for Byron? Some say Jimmie won't go much longer (maybe 2 or 3 more seasons) so that could be the vision.
Free agents in 2017 include Jamie Mac, Brad K, Denny, Kenseth, Menard, Larson, Almirola, and Erik Jones is technically not under contract. (according to

Most of those are likely to re-sign with their current team (Menard and Almirola possibly excepted, but probably not in consideration for the 5 anyway). But could HMS lure one of those guys away? Hmm
