Afterthought: Can I make money betting against Johnny Football?

Preseason football isn't something you'd like to bet on regularly, if at all.  NFL games where the coaches have literally nothing to play for means you can expect the unexpected.  There's no telling who is going to play, or for how long, etc.  Basically, they are scrimmages against other teams.

So, I was looking at the point spreads for Saturday night's Browns vs Lions game in Detroit... and I noticed that the Browns were giving up 1.5 points.  On the road.  At a very talented Lions team.  And yeah, it's preseason football, but it is football, and there's just no reason on earth why the Browns should have been favored in that game.
  Which led me to think about, and eventually realize, that the number was there at kickoff because of people betting on Johnny Manziel's first performance in a Brown's uniform.

I didn't put money down on it, but I absolutely should have.  Hindsight is always 20-20, but on the road, you don't normally win in the preseason.  14 of 16 home teams won their games this weekend.  That includes the Titans over the Packers, Redskins over the Patriots, etc.  They are practice games.

So here's what I'm doing for the rest of this year -- if the line looks fishy and it seems to be favoring Cleveland more than what it normally should... you can go ahead and bet that I've got money on the opposing team.  Vegas knows people will overvalue the media superstar.  We'll keep an eye on this as the season progresses.
