re: Grossman signs, Brady Q signs, whither Tebow?

The real reason is that you can't sign him to be your backup because he can't run the scout team and he's going to be so different from other QBs that if your starter goes down, the team is screwed (even more than teams would normally be)

So, if you sign Tebow, you're signing him to be your starter and designing your offense around his skills and he's not good enough to start anywhere so...
