Former Super Bowl-winning quarterback Joe Theismann is not that surprised that the Giants are 0-4.

Appearing on "The Mike Lupica Show" on ESPN NY 98.7 FM on Monday, Theismann said the team hasn't been that good in recent years, despite winning two Super Bowls.

"To be honest with you Mike, if you look at this football team over the three years you’re talking about, really the three years, even though they’ve won championships, they’re not that good a football team," Theismann said. "They’ve been inconsistent at the wide receiver position, whether it be by play or injury. The running back position has been suspect for quite a while, now you got guys putting the ball on the ground. Their defensive line has been hurt at times, and there’s been a great change there. And we know that their linebacking corps has been in flux, and their secondary has been average."

"Truthfully, Eli Manning has basically taken this football team on his shoulders over the last couple of years, and the success that they’ve been able to enjoy is because of the incredible way that he has played," Theismann added. "All of a sudden we see Eli struggling -- now you have to ask yourself if you’re a Giants fan, is this the real Giants football team, and I think the answer to that question is probably yes. Unless Eli plays at an incredible level, and protects the ball, then I think you’re basically stuck with what you see."
