It's a legitimate question five games into the season. The Cardinals are 1-4 and Kolb hasn't come close to looking like a long-term franchise quarterback.
He has been wildly inaccurate, and he's completing 58.7-percent of his passes. He has thrown five touchdown passes and six interceptions. His passer rating is 77.2, which is down near the bottom of the league and he turned it over three times in the Cardinals loss to the Vikings Sunday.
When I evaluated Kolb last spring, I saw the inconsistency in his game. He was accurate at times, but sometimes went wild. The Cardinals are seeing that wildness now.
The Cardinals could have taken a quarterback last April in the first round of the draft, but opted to make the move for Kolb.
It could be a move that sets this team back in a big way if Kolb doesn't get it going.
It's not like he doesn't have anybody to throw to since Larry Fitzgerald is his top guy. I do understand the Cardinals tackles aren't very good, and the pressure has been plenty, but Kolb hasn't played like a guy who can be the foundation of this franchise for years to come.
Where have you gone, Kurt Warner?
• Does anybody really believe the Jets denial that some of their receivers didn't complain about the play-calling? I don't. A report in a New York newspaper said that receivers Plaxico Burress, Santonio Holmes and Derrick Mason went to Rex Ryan and complained about the way the games were being called. The Jets moved to defuse the situation by sending out a statement. It read: "The New York Jets deny a report this morning that wide receivers Plaxico Burress, Santonio Holmes and Derrick Mason have gone to Head Coach Rex Ryan individually in the past few weeks to question offensive coordinator Brian Schottenheimer’s system." They should be questioning Schottenheimer. I think he is vastly overrated as a coordinator in part because he's chummy with a lot of media members. I ask this seriously: Do you ever come away from a Jets game thinking how impressed you are with the offense?
• About those receivers: Who besides Holmes scares down the field? Burress and Mason sure don't.
• Just when we think the Texans are ready for the big stage, they lose at home as a favorite. I won't believe until they show me they can win a game like this week's at Baltimore. Show some toughness -- for once.
• If Darrius Heyward-Bey can continue to play the way he did Sunday, catching seven passes for 99 yards and a touchdown, the Raiders can be explosive on offense. With Heyward-Bey and Jacob Ford, they have two of the fastest receivers in the league. Just the way Al Davis liked it.
• You have to love the toughness of Patriots running back BenJarvus Green-Ellis. He ran for 136 yards and scored two touchdowns against the Jets Sunday. Not bad for a player who wasn't drafted. By the way: He was on my Better-Than team the year he came out. Got one right there.
• Broncos quarterback Tim Tebow was 4 of 10 for 79 yards off the bench against the Chargers. But did run for a score and also bobbled three snaps. It's time for the Broncos to play Tebow. But let's not get caught up in the hype. He is far from being an NFL quarterback. Time will show that. Tebow looks like a paper being blown around in a windstorm when he plays quarterback.
• 49ers quarterback Alex Smith had a passer rating of 127.2 and threw three touchdown passes against the Bucs. He's playing a high level.
• The Jack Del Rio watch is on. I think he makes it to the bye week. The Jaguars play at Pittsburgh, then host the Ravens on a Monday night and then play at Houston before the bye week. If they lose all three, even a patient man like Wayne Weaver would have to know it's time. I've known Weaver for a long time and he will not tolerate an embarrassing loss on Monday night football. If Del Rio goes during the season, the word is linebackers coach Mark Duffner would be the interim coach. There is growing sentiment inside the building among other coaches and front-office staff that the time is right for Del Rio to go.
• Wonder how many in Philadelphia are questioning the move of Juan Castillo from offensive line coach to Eagles defensive coordinator? The Eagles are bad on defense.
