However, the C's need someone who is not a negative offensively.
This team is too good to put guys on the floor who are not at least passable on both sides.
Anything Jeffries could give them defensively, he would give back on the other end (and then some).
The same could be said for Perk and TA...and yet they each have/had their cheerleaders here on the blog...
The ticket with role players is that they have to fit with the rest of the lineup. Does the 2nd unit have enough offensive firepower to allow a role player with no O to fit in?
Perk plays Center, which allows him to get away with it without messing up the spacing nearly as much. He also is a more rare defender than Jeffries (meaning, it is much harder to find a center who can defend that well, as it is to find a perimeter guy who defends as well as Jeffries). Like I said before, if Jeffries is a PF, then it is a different story. You can hide a PF much easier than a SF. But in the C's offense, the SF needs to provide spacing that Jeffries can't provide.
And Tony Allen is 10 times times the offensive player that Jeffries is. Tony can get to the hoop, is a decent ballhandler (for a wing, not for a PG), and most importantly is a significantly better defender than Jeffries (at least last years Tony Allen was).
And the thing is, Tony did clog up the offense. That is why Doc tried so hard to get someone else in there in place of him. But, Tony's defense (last year) was able to overcome his offensive deficiencies.
I think part of the issue here is also that Jeffries is not THAT good a defender. If he were Ron Artest or Bruce Bowen, this would be a different conversation (he also would be playing regular minutes in Houston, and not being bought out). But he isn't. He is an above average defender, and that's about it.
