I think the entire experience with Joppru is colored by our previous bad experience with Boselli. When something like this happens and a player misses this much time it starts to smell like the Boselli situation to us and we all know how that turned out.
I don't really care to see Joppru this season. It's not like adding him to the roster is going to be the one missing piece we need to get past the Colts, win the division, and march on to the Super Bowl. If that's going to happen then it's going to involve a higher power than a tight end who hasn't played football since 2002. In short adding Joppru isn't going to make a difference to the Texans this season.
Sit him down, handle him gently, and let him come to camp healthy next season. If he blows that thing out again after all this time then yeah, start thinking of that as a pick that didn't pan out due to injury. Those things happen. For now we're ok at TE. We aren't great but we're ok.
