SEAHAWKS line from here, where does it go and end up closing in VEGAS? ??????????????????????? Some current lines.................. Cantor -3.5 -105 Southpoint, LVH, Nugget -3.5 Caesers, Aliante, Coasts -3.5 EV
With the line being on the other side of 3 you usually get drawn right away to the dog side. This one is a little different. Not only have I not bet yet, I'm watching the lines and CRIS and Pinnacle are out in front on Sea. You can get SF +3.5 -105 at CRIS while Pinnacle is at -3.5 -105. There is nothing in the money lines offered that suggest this number will gravitate to the 3 anytime soon but if it does take an across the board hit, I'd be doubly shocked if it's on Sea at this point. If you like SanFran I'd get involved soon. Maybe wait until -105 time at LVH tomorrow but that would be as long as I'd hold off. Losing that hook on the 3 would be a big downgrade. Getting the 4 would be nice, but losing the 3.5 and settling for 3 is not the way you want to bet. In the AFC, I wish I could say I got some of that +7 on NE at the open but I did not. Fortunately, there will be lots of options to bet on both games. The total is already getting bet up. Right now the weather looks good in both locations. 20% chance of rain in Sea. No real wind in either spot.
Thanks Frank, more thoughts or comments on this line from you or others would be appreciated.
I get nervous when any of the following happen on a local team: *Media coverage supports my theories *The line doesn't do what I predict *My square-ier friends don't disagree with me I have the trifecta here. I'd been saying for over a month that a SF/Seattle matchup in Seattle is a worst-case scenario for the 49ers. When they barely beat Seattle at home, it confirmed this for me. I have seen nothing since then to dissuade me either. I made the line for both games 7 after they ended. Can someone explain why they expect resistance at 4, that is, why it doesn't make sense to wait for the line to go up before taking SF? To me taking Seattle -3 was as obvious as taking SF pk on Sunday. My fellow fans sound like Red Sox followers in their cynicism of this game. Perhaps this has colored my thinking, although I think it reinforces it. I just don't get why SF is such a small dog, when both teams have shown me nothing to make me think the game will be this close. I have one thing that leans toward SF: Kaepernick, vs. Carolina, didn't hyperventilate and blow all of his time outs early, as he often has on the road vs. good teams. But perhaps Carolina isn't a loud stadium. I haven't done that research. I don't think he turned the corner on that, and unless SF spends this week focusing on helping him control the play clock, I don't see anything changing there. What is the coaching staff going to suddenly figure out now that they haven't figured out all season on this topic? For me the only play is Seattle -3'. Passing on the other game.
