Disagree. Collison was a part of the 5th strongest lineup last year. Most people preferred if we had upgrades at PF and SG last year, so with that in mind, it's very, very, very hard to sit there and say the third best player on the 5th strongest lineup in the league is a back up point guard. You have no ground to stand on, and you've given "nothing to support your claim that we will not make the playoffs with Collison starting." Is it just a hunch you have or is there some analysis behind it?
Are we talking about past or present day Rondo? I could tell you right now that I don't even think Rondo at his peak was a "perfect" fit for our starting lineup. Can he spread the floor? No, he can't. Therefore, you're "perfect" claim holds no validity. That was easy...
Look, I actually really liked Rondo's game back in the day when he was playing good basketball. A lot of the people here see the name "Rondo" and immediately get excited because they think of the all-star PG who won a championship. He has not been that caliber of player. Sure, you can take the risk that he becomes that player again, but you're putting your franchises future (by risking Cousins leaving) in jeopardy. I really only think this can go very good or very bad, and at this point, we should be limiting that risk (similar to what we did by drafting a guy like Cauley-Stein).
This team before Malone was playing stellar basketball. That same core is still in tact. There's no need to make brash decisions. Sign some veterans, improve the bench depth, & draft WCS (oh wait! we did that already!). There's no need to take a gamble on a player who could be boom or bust with the majority of our cap space (I'm assuming) who if doesn't pan out can also single-handedly destroy our team chemistry if he gets upset.
If we do sign him, I'm going to cheer for him as much as I can to become his old self and help us get to the playoffs, but from a logical standpoint, I would not like the signing.
