I'm pretty sure in order to sign a player to a Max Contract Bird's Rights is the prerequisite. Based on yrs in the league J.R. is entitled to a Max of 30% of cap, but no team has full BR's with him.....so I don't think he can make more than non-tax full MLE from anyone.
EARLY BIRD EXCEPTION -- This is a weaker form of the Larry Bird exception. It also allows teams to exceed the cap to re-sign their own free agents, but with more limited contracts than the Larry Bird exception. To qualify for this exception the player must play for two seasons without clearing waivers or changing teams as a free agent (see question number 32 for details and nuances to this rule). A team may use the Early Bird exception to re-sign its own free agent for up to 175% of his salary in the previous season2 (not over the maximum salary, of course) or 104.5% of the average salary in the previous season, whichever is greater (see question number 31 for the definition of "average salary"). Early Bird contracts must be at least two seasons in length, which prevents teams from using the Early Bird to sign a one-year contract, then signing the same player with the full Larry Bird exception the following season. Early Bird contracts can be up to four years in length, with raises up to 7.5% of the salary in the first season of the contract. Early Bird is also a component of the Veteran Free Agent exception, and qualifying players are called "Early Qualifying Veteran Free Agents" in the CBA.If the player is a restricted free agent with two years of service and qualifies for the Early Bird exception, then the player's prior team may use the Early Bird exception to match an offer sheet he receives from another team (see question numbers 43 and 44). This is true even if the starting salary for the Early Bird exception is lower than the starting salary of an offer sheet, which is based on the Non-Taxpayer Mid-Level exception.
A team can renounce its Early Bird rights to a player, and instead re-sign him with the Non-Bird exception (see below). They might do this in order to sign the player to a one-year contract, instead of the minimum two years required by the Early Bird exception.
Starting January 10 of each season, this exception begins to reduce in value. See question number 26 for details.
He's not a restricted Free Agent, so he can't get a contract offer similar to Lin's. We can't sign him to a 1 yr deal, then Bird's Right him the next.
We have to sign him to a 2-4yr deal at 104.5% of whatever the "average salary" comes to be for the 2012-2013 season, which is estimated at this time to be approximately $5.275mil. If we sign him to a 2yr deal, then we can offer him a BR contract after it expires as he/we would have obtained full BRs, 4 season in total played with Knicks in succession.
I've yet to see anywhere, where Smith can get anything above this from any team. Dollars to Donuts he can't/won't make too much more than $5.275mil/yr anywhere.
