It is hard to understand what is happening to Monroe. I think he got a little over-rated; his best seasons were something in the range of 16 pts /10 rebs and always shooting at a high percentage. That is productive. I have not seen him actually play in a while (I trust my eyeballs much more than stats) but I remember him as a decent defender and team player.
It is hard to know what is going on but there is probably still an upper tier big in there somewhere. If you add that to the Celtics and start him along side Horford, I believe we get quite a bit better than we are now (assuming the trade is Johnson/Jerebko or Johnson/Zeller plus a not so valuable future pick).
In terms of the fear of keeping cap space, that is kind of like drafting, you really never know what you are going to get. Last year we got Horford, big whoop. I would hate to think we didn't do a trade just to overpay the next Al Horford. I would do a trade for Monroe under the following conditions:
- I get to see him play and get reassured that he is still the same Greg Monroe, just in a funk of some sort
- That the trade is Amir and not all that much more
With those things, i do the deal and don't worry about the future FA we might get next off season.
