Only four remain in the Ravens best-ever free agent tournament

And only four remain.

And only one No. 1 seed is left standing. Derrick Mason, who I made the top overall seed, defeted Tony Siragusa in the quarterfinals by a margin of 65 percent to 35 percent. It was the widest margin of any quarterfinal matchup. The other three No. 1 seeds made it to the quarters but were unable to advance.

Jacoby Jones defeated Michael McCrary in the closest matchup, a 52-48 win. Shannon Sharpe beat Rod Woodson 55-45 and Matt Birk defeated Elvis Dumervil 60-40.

Here's how the final four looks:
