My son pointed this out to me and it makes sense. There are now quite a few teams out there with highly mobile qbs who like to run more than pass. There are even two in our division. Using Tebow as the scout QB all week gives our defense a chance to practice against a real QB playing that positioninstead of a db playing that position in practice
In the meantime, if they can get him to correct his throwing motion and to look for pass first before running, he might develop into a good QB over time. Remember, he will only be 27 in 2017. One thing to remember is that the guy *is* a winner and he *is* big. he won't get a single snap this season in a game unless (I hate to even say this) Brady goes down and Mallet sucks wind.
So, all in all, I think BB made a great move -- if only for paragraph #1 above.
