The problem with the Betts matchup isn't the Saints defense ... because they can be run on. The problem is the Saints OFFENSE. They can run away with this one early, thereby taking the bulk of Betts' workload with them.
The 'Skins running game may be rendered moot by halftime. Can Betts do enough damage given these circumstances? It seems as if Gibbs/Saunders will stay commited to the run (Betts got decent work last week down 21-3 to Philly) ... it's a crapshoot, at best.
Bright side for Betts/'Skins? Perhaps the Saints come WAAAAY down after that huge win vs. Dallas.
Conversely, FWP has had 10 days rest ... coming of a career best game. Yeah, he has his troubles on the road, but I like the Steelers chances of being "in" the game, possibly with the lead, more than the 'Skins.
So, it appears as if FWP has the better matchup.
