Mark Clayton is headed for the best fantasy year of his career and that is with or without Derrick Mason on the team (Mason announced his retirement in July of '09). He had a breakout year in his 2nd year in the league in '06 when he went for just shy of 1,000 receiving yards and five TDs in the only year that he has had a QB with a strong arm throwing him the ball. That QB was Steve McNair (RIP) who was murdered by his guma in July which coincidentally led to Mason's retirement. Clayton's game is a vertical one; he is a big play WR in the vein of a Santonio Holmes, and playing with noodle-armed losers like Kyle Boller for most of his first four years has really set him back. Joe Flacco has a strong and accurate arm but was limited in his attempts in his rookie year, and should be let loose a bit this season as he becomes more comfortable in Harbaugh's scheme.
Last year, the Flacco targeted Clayton 82 times to Mason's 121, and given the recent retirement of Mason (we think he will come back, though, as he is also unhappy about his contract), Clayton becomes the primary target.
