The thing is, we already know what we have in Bledsoe and he is just not going to take us where we want to go. He would be decent on a team without playmakers at WR/TE but a max protect oline and a big bruiser back. After the last few times seeing bledsoe though really, even in that situation I'm not so sure his decision making would allow him to win there either eh... real negative on him at the moment. We have exactly the opposite of what would make Bledsoe a decent qb, all we do have that sorta cater to him are deep threats that let him chuck the ball deep.
With Romo he at least alleviates the end all be all counter to the current Dallas cowboys team, which is blitz Bledsoe and force him either out of the pocket or into a hurried throw (his hurried throws are freakin terrible every time) and that alone demolishes the entire offense. Bledsoe is not going to take us to the superbowl, we might beable to get to the playoffs with him but any decent playoff contender is going to game plan around Bledsoe and most likely win the game off of that alone.
If we let Romo go early, he'll play enough games throughout the whole season so that come playoff time he can possibly be ready. We got some easy games after the skins here, here's to hoping badsoe chokes up a storm against the skins (but we still win) and bringing in Romo over the bye week to get started against some of the easier teams... tenn/houston notably.
