Gortat would be the perfect fit at backup for Perk, and here's my reasoning:
1.) We wouldn't lose a great deal of what Perk brings to the game, mainly solid interior defense (one on one and team D) and fundamental rebounding/finishing near the rim. So many times this postseason when Perk left the game, the interior defense sputtered, and other teams were able to work inside. Especially with the Lakers being as big as they are, and with Howard who will only get tougher for Perk in the coming years.
2.) Could you imagine twin-tower tandoms of Perk-KG, KG-Gortat, OR Gortat-Perk. These twosomes would wreak havoc on any penetration, and also hold in check big time big men like Howard etc.
3.) Gortat is only 25, and doesn't seem the type to slack off. He is a workman, someone who punches his timeclock when he steps on the court, without much complaining or talking.
For those of you who have been preaching Sheed, I would preach the exact opposite, which is Marcin Gortat. This guys is the real deal on D and rebounding, and is the consummate backup Center. I'm sure he'll want more than the MLE has to offer, but he's worth taking a gander, because I believe he would fit so well in this system.
