CLEMSON -- Clemson two-sport star Kyle Parker said he believes negotiations with the Rockies will drag on until Monday's signing deadline.

Parker said coming to an agreement with Colorado has been especially difficult since so few draftees have had as much remaining football eligibility as the Clemson quarterback.

If Parker does not sign by Monday's deadline, he would likely return to play a fourth year for Jack Leggett next spring.

Still, the odds are with Parker signing a contract. Only two players drafted in the first round of 2009 did not sign. Parker was selected 26th overall by Colorado in June.

"I think they are getting better," Parker said of talks. "We just need to figure it out and get to common ground."

Parker says there are a lot of "moving parts" with his negotiations. Not only does the Parker camp have to come to terms on a signing bonus number, but he has to make a decision on how much football to buy out. Parker said the talks have ranged anywhere from signing a baseball-only deal, beginning next year, to plans to sign a deal that would allow him to continue playing football for multiple seasons.

"The biggest thing is there is a whole lot of language to figure out," Parker said. "We are talking more frequently … We are talking about things (like playing football beyond 2010) and obviously they are going to have things in there to protect themselves."
