With the Packers reportedly $21.5 million under the salary cap after giving star WR Greg Jennings a three-year contract extension averaging almost $9 million per year in late June, team insiders tell us the odds are strong that there will be a fair amount of wheeling and dealing in July involving the seven remaining starters entering their contract years. Word is the odds are equally strong that Pro Bowl FS Nick Collins will become even more unhappy than he already is if he isn’t first in line at the bargaining table among those seven starters, which apparently is quite possible. The way we hear it, it’s more likely that, in no particular order, both starting OLG Daryn Colledge and Jason Spitz, who is expected to replace Scott Wells as the starting center, are better bets to sign new deals before Collins, who has hinted that he might stage a training-camp holdout if his contract concerns aren’t dealt with soon.
