Look, Savage (and Weeden) are longshots, and beyond the fact that they haven't failed to this point (well, in Weeden's case, he hasn't failed as a Texan to this point), there's no reason to believe either is the answer beyond the "We could find lightning in a bottle" argument that dissatisfied fans are so vulnerable to. Look at the history of QB's in the NFL (semi-recent history anyway), and as far as I'm concerned, the ever-dwindling chances that Osweiler could turn things around and become a serviceable starting QB for a team with Super Bowl aspirations (which doesn't need to make him Tom Brady or Aaron Rodgers) are still better than the chance that the 4th round pick with 19 NFL passes and two season ending stints on IR or the guy on his third NFL team who's record as an NFL starter prior to joining the Texans was 5-19.
We've invested $37 Million into Osweiler with an option to invest another $35 if things do an incredible turn-around for him. I don't think sitting him does anything to teach him a "lesson", nor does standing on the sidelines listening to his helmet and watching someone else run this team help him learn much. If that were the case, his 3+ years watching a HoFer ply his trade would have done more than it apparently did. I'm not saying you can't learn by observation, but I'm saying that method has been utilized already, and even then, you learn more by doing than watching.
Brock Osweiler looks more and more like he'll be getting Spencer Tillman's proverbial apple and roadmap at some point before the 2018 off-season gets underway (with apologies to those who are as tired of that phrase as I am), but given where we were before he got here, and where we'll very likely be if/when he's a cap casualty, I want to be absolutely 100 percent freekin' positive this guy is an NFL washout before we move on to whoever the next great thing that might hopefully turn into our long hoped for franchise QB (if the good lord's willin', and the creek don't rise of course). Even for one game.
