‘After spending the last couple of seasons chasing Bills diminutive quarterback Doug Flutie, you would think Jets linebacker Mo Lewis might be relieved to be staring down Rob Johnson instead when Buffalo comes to Giants Stadium tomorrow with both teams 2-0 atop the AFC East. Not so fast, considering Johnson is no slowpoke himself. "He’s a good quarterback and brings a lot to their team," Lewis said yesterday. "Flutie had to create his own throwing lanes, but Rob doesn’t have to do that. That’s one of the advantages for him." Indeed, Johnson stands tall in the pocket at 6-4 and 215 pounds, while the 5-9 Flutie had to be more creative to see through the mass of humanity in front of him in the trenches. Still, Lewis came to respect Flutie as "a tough competitor," although he prefers not to discuss the blind-side block the little guy cut him down with on a reverse last season during the Jets’ 17-3 loss at Ralph Wilson Stadium. "I know what you’re getting at," Lewis said when asked about his most vivid memory of Flutie. Then he smiled and walked away, refusing to bite.’
