Any poker player could relate to the 49ers.
They started with what seemed like a promising hand. They placed a significant amount of chips toward the center and stuck it out even when the hand appeared less promising. They finally realized there was little sense in folding based on how much they had already invested and how little more they stood to lose.
They were pot-committed.
Quarterback Alex Smith is that once-promising hand. There's little sense in folding at this point. If anything, the odds for success improved after Smith finished last season with 18 touchdown passes and 12 interceptions playing basically half the season.
But what if the 49ers could ditch this hand in favor of a more proven one? What if the price were not prohibitive? What if they could acquire Donovan McNabb from the Eagles for, say, a second-round choice in the 2010 draft?
The 49ers already have two first-round choices. They could draft the offensive tackle they need and still get a potential starter at another position. The Eagles already have an extra third-round choice. An additional second-rounder would leave them with five choices in the first three rounds, tied with the Browns for the most in the league.
Let's look at this deal from an NFC West perspective. Would the Cardinals, Seahawks and Rams rather face the 49ers with McNabb or the 49ers with Smith and whichever player San Francisco drafted in the second round? I think they'd rather take their chances with Smith and the 2010 second-rounder.
Take a look at the last 10 players the 49ers have drafted in the second round: Chilo Rachal, David Baas, Justin Smiley, Shawntae Spencer, Anthony Adams, Jamie Winborn, John Engelberger, Jason Webster, Jeremy Newberry and Marc Edwards.
Some became good players. None could affect games the way good quarterbacks affect games.
Some Eagles fans are tired of McNabb. They think Philadelphia has gotten as far as McNabb can take them. They're ready for a change. The 49ers can have no such complaints. They haven't been a playoff team since 2002. They would gladly "settle" for multiple playoff appearances and a quarterback with a 92-49-1 (.651) regular-season starting record, according to Pro Football Reference.
