NFL: Source: Colon's agent trying to gauge interest from 49er's and Packers

The Pittsburgh Steelers placed a first round tender on starting right tackle Willie Colon last month that will pay Colon $2.521 million in 2010 with the intention of having their starting right tackle back in the fold.

Colon's agent Joe Linta, however, has been frustrated by the lack of long-term contract negotiations.

"We really don't know if he fits in their (long-term) plans," Linta told the Tribune-Review in early March. "Now we have a chance to look at teams in the first round of this year's draft between 12 and 32 and see if they'd be willing to give up their pick for who I believe is the best right tackle in football.

"If you have the 15th pick and you need a starting offensive lineman, why wouldn't you do it (make a trade)? You hope your draft pick is good. With Willie, you know what you're getting. He's a young guy (26) who's still got 8-10 years to play."

With just three days until the deadline for offer sheets, Linta has backed up his statement and according to a source, Linta has been aggressive in the past 7-10 days in trying to find a potential suitor for his client.
