If the Ravens are seriously pursuing Arizona Cardinals' wide receiver Anquan Boldin, the competition may have just thinned out a bit. Maybe a lot.

Reportedly, the Philadelphia Eagles -- who were also thought to be in the hunt for Boldin -- have agreed to trade a first-round pick to Buffalo for the Bills' two-time Pro Bowl left offensive tackle, Jason Peters. Obviously, the Cards want a first-round pick for Boldin and a little extra.

If that Eagles-Bills trade goes through (there are reports that Philadelphia wants Peters to agree to a contract extension), it probably eliminates the Eagles from any more big moves leading up to the draft. Philadelphia had two first-round picks (No. 21 and No. 28) and 12 choices overall.  The Eagles gave up the No. 28 and two other picks (a fourth-rounder this year and sixth in 2010) for Peters. 

Meanwhile, the Ravens have the No. 26 overall. Certainly, the Eagles could still try to trump a Baltimore offer with their No. 21 but it also would seem unlikely that the Eagles would give up another first-rounder in a trade, not to mention the payroll strain of coming up with fresh bonus money for both Peters and Boldin.
