I'll try to make this brief -
We've begun to focus on the wrong thing here, I think. I seriously doubt that many players here are developing into serious role players in the NBA. Let's call a spade a spade. Except for Zeller, I'm seeing a bunch of highly flawed, upside and downside bench players. Avery is volume shooting defensive whiz. Green is a streaky sixth man. Bass is, at best, a 3rd option off the bench. Sullinger is an out of shape and malcontented power forward who can't quite jump like a pf. Sully at his best could be zack Randolph but he reeks of a guy with commitment issues. Olynyk seems like a smart player and could be a scorer, but definitely lacks athleticism.
Anyway - MOST good to great players in the nba are pretty obviously good from the moment they step on the floor. Look at Jabari Parker for example.
So, taking this all into account, putting it together with how Ainge has been setting up his hand, and taking into consideration his past tendency to make big moves, I think Danny intends on big trades or big free agent signings.
It annoys me when people say basketball players don't want to come to Boston. Why not? Since when? According to whom? Baseball players come here. Football players come here. Hockey players come here. And this offseason we will have more money than nearly any other team to spend on high end elite talent.
Jimmy Butler is a restricted free agent. He is number 3 on Hollinger ratings of SGs. That would slot Bradley into his more appropriate bench role. Lemarcus Aldridge is, I believe, number 5 for PF on hollinger stats and an UFA. Marc Gasol I'd, I think, number 2 for centers on the Hollinger list and is also an UFA. We likely have salary to offer two max deals AND the new TV money will be coming in, allowing payrolls to go up. Fill in the team year by year with Fresh talent using the multitude of picks and trade away extra players on expiring contracts for picks year by year. ONLY THEN will Stevens and Ainge be able to implement a Popovichtype system in Boston.
Also note that there are other high end talents coming through. After next season, Anthony Davis will be RFA and if the Pelicans aren't contending he may want out.
Quite honestly, a sport like baseball is more useful to have realism in for your teams acquisitions, due to the fact the team is much larger and therefore each players role much smaller - a team can be built on chchemistry and shrewd incremental decisions.
Basketball on the other hand should have its fanbases pushing for high end talent year in and year out. If we pessimistically say "well, no free agent is coming here." And "in 5 years one of these kids will be a nba starter!" Or "if Brooklyn keeps going downhill, our picks in 3 years will be solid" then you've got a losers mentality.
Hey maybe that's why free agents don't come here. Maybe this stuff trickles to them. I mean, there was a time when no one wanted to go to Oklahoma. Now players are excited for a chance to win.
Snag a big fish and use that fish to lure others. Let's be positive and start asking for some big and impressive changes!
