At this point, why trade him? You are not going to get anything of value back. It more likely he turns things around and becomes a solid contributor than it is finding anyone via trade that could help this team as much as Rozier. He has unfortunately played his way into being so bad, he is now worth more to us than anyone will give you in return for him.
I agree with this, if Danny wanted to trade him, it would have been this offseason when his value was higher before integrating Kyrie back into the starting lineup and eating away his minutes and leading a team.You don't dump a stock when it is down and crashing unless you absolutely need the liquidity. Right now is the worst possible time to move him.
My guess is that Danny is well aware of Kyrie's injury history and does not want to risk leaving this team with Smart leading the point for a good chunk of time. That is exactly what you will get if Kyrie goes down. Cleveland fans tell me constantly(work with them) that just wait, Kyrie gets some sort of injury like clockwork almost every year. There is no avoiding it.
Since he has been in the league, he has played in the following game in regular season:
60-missed all postseason
Those numbers do not scream trade away your back up.
In 2015 Finals, his knee collapsed. Last year he missed the entire playoffs and a huge chunk of games. In fact, in the past 3 years, only once did he play more then 70 games. Imagine this team with Smart leading the point for 30 games like in 16? Yikes.....But to be fair, that season he came back to lead them to a title with the dagger shot. When he plays, he is amazing...No doubting that but to think that he suddenly will become durable is probably not very realistic.
This latest injury is not an easy one long term as well. Here is a good article on the details of it.https://theinjuryinsight.com/kyrie-irvings-knee-injury/
My guess is he stays for the year unless Danny can trade for a legitimate backup PG and he will facilitate a nice contract for him to someone else for an asset or two. We then sign a backup PG in the offseason. This will secure our chances this year in the event of another injury. In addition, Rozier on the 2nd unit in the playoffs will be awesome for us.
