The reality on the ground is that it is bad for the Raptors (in the long run) if BC tries to hold out on Bosh over a 6th year if Bosh does deceide to leave....especially to a team that can sign him as a FA.
I agree the player and agent have the upper hand. I also think if player and agent in this case Bosh and Thomas try to force a threat of "OK 5 years see ya" and divorce themselves from the machinations of players/picks/locations involved then the agent also burns a major bridge is this relationship as well. The Rashard Lewis signing will not be the precedent here. I am pretty sure for an extra year and maybe 30 million dollars they give the Raptors more options than the Rashard Lewis fiasco. I do not think the folks at MLSEL would think that the Lewis return was in any way protecting their investment. I also think the Raptors are not stupid enough to go past the deadline without some understanding for S+T. Not a chance. If Bosh and Co. were to have gone all cagey on them or pulled a Vince Carter he would have been gone at the deadline or last summer.
