The window opens Monday for NFL teams to renegotiate or extend the contracts of first-round picks from the 2011 draft. But negotiations don't figure to be easy with players who are still more than two years away from unrestricted free agency.

GETTING BETTER: Panthers' Smith improving, won't play

That's especially true for the players in a remarkably productive top 10 who would make the average of the 10 highest prior year player salaries at their position in 2015 if no long-term deal is reached and they play under the fifth-year club option that must be exercised by May 3 instead.

At least four of the players in that top 10 -- Carolina Panthers quarterback Cam Newton (drafted No. 1 overall), Cincinnati Bengals receiver A.J. Green (4), cornerback Patrick Peterson (5) and Atlanta Falcons receiver Julio Jones (6) – figure to be targeting bar-setting type deals.

Two others, pass rushers Von Miller of the Denver Broncos (2) and Aldon Smith of the San Francisco 49ers (7), could do the same eventually if they can put their off-field issues behind them over the next two years.

Same with Houston Texans end J.J. Watt (11), though because he was taken outside the top 10, his fifth-year option would be worth less – the average of the third through 25th highest salaries of players at their positions the prior year.

Any option exercised is guaranteed for injury only until the fifth day of the option year, when it would become fully guaranteed if the player is on the teams active/inactive roster.

Clubs moving quickly to extend those players do so at their own risk. No matter the price tag, the market only figures to inflate as the salary cap rises, meaning those same players could be looking to renegotiate again by the time March 2016 rolls around if they continue to produce.
