I gave out Dallas +6 2 weight, I'd grab it now

I gave out Dallas +6 2 weight, I'd grab it now Line will drop IMO.........
Why's this line down to 4.5? It's tempting to buy the hook and shoot for a middle here.
Because the 'right' line is MIa -4.75 VEry closely contested series, AND HFA could crumble if Mia starts slow tonight.
do you come back miami -4 -120? or not enough middle. personally i think miami wins this game easily but then game 7 is a last shot war...
