And what makes you think Kenneth Faried would have been a quality backup for Amar'e? Faried is too small to play the 4 against most teams in the NBA. He'd serve as an offensively-crappy backup for Carmelo, at best.
Instead of having Kenneth Faried back up Carmelo and having crappy defense in the backcourt because Fields, as competent a player as he is, isn't quick enough to guard the 2 position reliably, having Shumpert allows us to not only improve our backcourt defense (which we all agree is a huge weakness) but also improve our backup at SF (better backup for Carmelo in the form of Landry Fields).
Having Faried addresses our rebounding needs when Carmelo/Amar'e is off the floor but does nothing to address the fact that our backcourt gets constantly abused by any team with a half decent 2 guard who can take the ball to the basket. I'm tired of seeing the likes of Nick Young and Louis Williams embarrass us. We need a shooting guard who can play lockdown defense, we've needed that for a long time, and having a guy like Iman Shumpert who can fill the Tony Allen role on our team is going to be pivotal.
While having Shumpert, we can fix our backcourt defense AS WELL AS have a decent 2nd unit in the front court by giving Landry Fields the primary 6th man spot behind Carmelo. It improves our team because:
1. Our backcourt defense is no longer shit
2. Our frontcourt has a decent backup on offense when Carmelo is resting on the bench.
If you put Kenneth Faried on this team we're going to score shit for points when Faried is on the floor. If we put Shumpert on this team we get better defense in the backcourt from our starting lineup AS WELL AS, because we shift Fields to the 2nd unit, a better offensive team when Carmelo is resting. Plus we have a player like Fields who can rebound as well as Carmelo can.
At the end of the day though, we both recognize this team has some serious problems - backcourt defense, depth at the forward positions, and REBOUNDING.
And the reality of the matter is the only thing that will solve our rebounding woes is a CENTER. A HALF-DECENT Center who can rebound and block a shot here or there. Kenneth Faried is not that guy.
But you know what the WORST problem of all is?
This all could have been solved if the Knicks just kept COREY BREWER!
Seriously! Brewer is an excellent athlete who is also an excellent defender. He could have been the PERFECT player to play behind Carmelo, then we could have drafted Shumpert and traded him or drafted Shumpert, put him in the starting lineup, and traded Fields for a bigger guy who could play behind Amar'e. I still think waiving Corey Brewer is going to bite us in the ass because I thought he was going to be the unsung hero of the Carmelo trade - instead he gets waived because he doesn't shoot 3's so Mike D will never play him. Instead he'd rather play Roger Mason Jr. Wow.
