That would really be rolling the dice for Bledsoe. I do not think that is good advice from the agent. Take a 1 year 6.5 million deal, when a 4 year, 48 million deal is on the table? That is a pretty big gamble to take with a player's money.
Contracts and circumstances change quickly in the NBA. I love Bledsoe, but if he had another knee injury and missed half the season next year, I don't think his next contract would approach 4/48. I understand the player feeling a little undervalued, but that is what agents are supposed to be there for. To be a cool head in a stressful situation. Bledsoe could continue to improve and deserve the max contract (a la Joe Johnson), but I think a path similar to Eric Gordon is also entirely possible. A lot of Bledsoe's value comes from his potential as a player. An injury or regression in his outside shooting could really hurt that value.
If his agent is just posturing to get the Suns to kick in another couple of million, he is playing it well. If he gets a 24-year old kid with two fairly serious knee injuries to reject 48 million and play on a one year deal, then I think he is gambling with other peoples' money.
