Danny obviously has to shop around. And personally, I'd still give the edge to Aldridge as the preferred FA big out there. At this point in time he is a better player overall than Monroe. But one of the reason's he is better is because he is more experienced (almost 5 years older) and he will cost 18.8M per to start his contract this year. So it's not a huge edge when you consider cost/value. So I'll be glad if Danny can lock up either one of these guys.
I didn't read your post before I posted, and ended up saying almost the same thing you did haha
This part is an interesting point though.
If you look at his first few seasons in the league, Aldridge never really looked like a superstar until around his 6th season.
His per-36 numbers over his first 5 seasons were:
Age 21: 14.6 /8.1 / 0.6 / 50.3% FG
Age 22: 18.3 / 7.9 / 1.7 / 48.4% FG
Age 23: 17.6 / 7.3 / 1.9 / 48.4% FG
Age 24: 17.2 / 7.7 / 2.0 / 49.5% FG
Age 25: 19.8 / 7.9 / 1.9 / 50.0% FG
All good numbers, but not really superstar good.
It wasn't until his 6th season (age 26) this his scoring numbers jumped dramatically (21.5 Points Per 36) and it wasn't until his 8th season (age 28) that his rebounding also jumped (11 Rebounds Per 36) to really put him on superstar level.
Monroe only just finished his 5th season, and his per-36 scoring numbers have shown a similar pattern over his first 5 seasons:
Age 20: 12.2 / 9.7 / 1.7 / 55.1% FG
Age 21: 17.6 / 11.0 / 2.6 / 52.1% FG
Age 22: 17.4 / 10.4 / 3.8 / 48.6% FG
Age 23: 16.7 / 10.2 / 2.3 / 49.7% FG
Age 24: 18.5 / 11.9 / 2.4 / 49.6% FG
Neither guy has been known as defensive stoppers or rim protectors, so really the only key difference I see between the two is that Monroe has been a great rebounder ever since his rookie year, where as Aldridge took 8 years or so to make the jump from an average rebounder to a great one.
Monroe started in the league at a similar age to Aldridge (21 vs 20) and like Aldridge his fifth season (this season) was a bit of a breakout season for him offensively.
Even Demarcus Cousins (who also started at a similar age) didn't really break out until his 4th season - after his first three seasons people saw him as a similar caliber player to Monroe...nobody had a clue that he was going to explode the way he did.
So how do we know that Monroe wont make the same kind of jump next year that Aldridge made in his 6th season, and that Cousins made in his 4th? How do we know that Monroe won't have a breakout year, and come out as a 22/12 guy?
This is especially true for Monroe because of how poorly he's been utilized in Detroit - with him moving to his natural center role full time, on a team with proper coaching and management, plus yet another year of development (possibly adding a midrange jumper to his skill set) - who knows how good this kid could become?
Plus think about it, what's the likely worst case scenario here? He doesn't end up getting any better than he is right now, and you end up paying $17M a year for a 6'11", 250 pound, 17/10/3/50% FG guy who you can depend on to suit up for you night-in and night-out because he doesn't have a history of injuries, foul trouble or suspensions.
You really could do a LOT worse.
It's a low risk move with the potential for a very high reward. Opportunities like that are pretty rare, and if that chance is on the table as a GM, you take it.
