With a little less than half the NFL season under its belt, the last thing that any contending team would want to endure is a quarterback change.

But, of course, we are talking about the National Football League – and on a weekly basis you never can tell what will happen next.

Let’s look at some of this week’s most noted moves and examine the sensibility of each:

Redskins Replace Rex Grossman with John Beck

In Washington, there’s no such thing as a level of comfort. Take, for example, the running back position. Tim Hightower, a local favorite and native of the DC area, was replaced after Ryan Torrain ripped through the St. Louis Rams defense a couple of Sundays ago. So, if running backs have that much turnover, one can only imagine the volatility with a position as critical as quarterback. Rex Grossman, whose play (and QB ratings) has continuously declined after a remarkable opening week against the Giants, was given the hook by head coach Mike Shanahan. His performance really hit rock bottom against Philadelphia, as he tossed 4 picks, no touchdowns and only completed 41 percent of his attempts (to his own teammates, that is). John Beck got his feet wet in his first NFL action of the regular season, and only appeared to be marginally better than Grossman. Only time will tell regarding the longevity of this move, but we all can rest assured that neither one of these guys is the final answer for Shanahan.

Tim Tebow Takes the Reigns

Ever since the hyped training camp battle that apparently never existed, Ball or Nuthin’ has encouraged John Fox to make this move sooner rather than later. Tebow’s finally going to get his shot, and it only makes sense – because this franchise really isn’t headed anywhere anytime soon.

McNabb Goes to the McBench in Minnesota

The time is now in Minnesota. Surely, Donovan McNabb can still make plays that others can’t – he just hasn’t made any of them so far this season. He says that he has “lots of football left” in him, but he hasn’t let it out for others to witness over the past two NFL campaigns. The Vikings have a retooled defense that still features names like Antoine Winfield, Jared Allen and E.J. Henderson. And, of course, they have a hefty contractual agreement with a fairly good running back. There’s no doubt that McNabb was feeling the heat. He put up his best performance of the season, connecting on 19 of 24 pass attempts for 177 yards (0 TDs, 0 INTs). But a 1-5 record is a 1-5 record, and this is not the McNabb that we all grew to love in Philadelphia.

The Raiders took a huge gamble on their acquisition of big-name quarterback Carson Palmer.

Desperate Raiders Nab Carson Palmer

Admit it Raider fans – no matter how much your team does not rely on its quarterback’s ability to air it out, you probably thought Oakland’s great start was about to go up in smoke when Jason Campbell went down with a collarbone injury. But the Raiders preserved your hopes for a somewhat special season, and put the Cincinnati-Carson Palmer saga to an end…albeit at an unbelievably high price. A 2012 first-rounder and a 2013 second-rounder (that has an outside chance of becoming another first-rounder, if the Raiders reach the AFC Title Game over the next two seasons) for a quarterback who had considered himself retired? Palmer admittedly has some rust to knock off and he’d better do it quickly – all indications point to him starting this upcoming Sunday against divisional rival Kansas City. The bottom line is that Oakland didn’t want to write off this campaign, so they rolled the dice on a high-stakes gamble. Will it pay off? If so, there’ll be two satisfied teams instead of just one.
