Input: The Philadelphia 76ers have agreed to a five-year  $148 million max rookie contract extension for  fourth-year center Joel Embiid   according to ESPN's Adrian Wojnarowski.
According to Wojnarowski  if  Embiid  hits the max criteria over the course of the deal  it could be worth as much as $178 million.
As such  the 76ers are taking a massive gamble on  Embiid  after just 31 career games. Embiid  the No. 3 pick in the 2014 draft  missed the first two seasons of his career with foot injuries before playing 31 games last year â and then missing the rest of the season with a torn meniscus.
But those 31 games were a revelation.  Embiid  averaged 20 points on 46% shooting  36% from downtown  with nearly eight rebounds and 2.5 blocks per game. With Embiid on the floor  the lowly 76ers actually outscored teams  competing with opponents for the first time in years after undergoing a dramatic rebuild.
The Sixers know what they have in  Embiid  on the floor â an athletic  inside-out  physical specimen capable of defending the rim and taking over the game on offense. The question is how often they'll get to have  Embiid  on the floor.
Sixers coach Brett Brown has already said the team is being extremely cautious with  Embiid 's health. He has sat out parts of training camp this season  taking part in 5-on-5 drills only occasionally. Few believe he'll play a full  82-game season soon. ESPN's Zach Lowe estimated that in order for the 76ers to be a playoff team  they'll need at least 50 games out of  Embiid   a modest projection that is still nearly double what he played last year.
If  Embiid  can't get over his injury woes  the 76ers will be saddled with a long  expensive contract for a player who can't get on the floor. According to Wojnarowski  the deal contains some "salary cap protection" for the 76ers if  Embiid  suffers a long-term injury  though it's unclear what the guarantees and non-guarantees are at this point.
But when  Embiid  is healthy   he  can do things like this:
The 76ers have decided that however much of this they can get from  Embiid  per season is worth it.
If  Embiid  recovers from  his  physical ailments and can play at least over 50% of the season annually  then the deal will be worthwhile. Stocked with back-to-back No. 1 picks in Ben Simmons and Markelle Fultz  the Sixers have a core that may be the most promising in the league.
But until  Embiid  is healthy and stays healthy  the team will always have a big question hanging over it.

76ers' contract extension for Joel Embiid a massive gamble
