Reports, including from this very website, are that Bogans is getting paid approximately $5 million to be involved in the Celtics-Nets deal. This makes no sense to me, from a cap perspective or a Celtics management perspective, or even from a negotiating perspective from Bogans agent. Here's why, with salary data from shamsports:
Without Bogans, the Nets are sending out $24,104,807 in salary (assuming the players involved are Humphries, Wallace, Brooks, and Joseph I've seen Tyshawn Taylor also mentioned, but I think he's not involved). This would allow them to take back $30,231,009 in salary from the Celtics. The Celtics are sending $33,792,319 in salary, which includes Jason Terry's 7.5% trade kicker. Accordingly, in order to make the salaries match, Bogans would need to be paid a shade under $2.85 million in year one of his deal to make salaries match between the two team.
Therefore, why would the Celtics pay him almost double what they need to? The 10-year vet min salary, which Bogans is certainly looking at if he is not involved in this deal, is $1.4 million, so by being a part of the deal, Bogans is already making 100% more than he otherwise would have, so his agent wouldn't seem to have much more leverage to demand so much. Furthermore, by taking on so much extra contract, the Celtics will find it much harder to get under the luxury tax level, which would likely be a priority for ownership if they're not fielding a contender this season.
None of this makes sense, so I hypothesize the reports are wrong, and Bogans is being paid between $2.8 and $3 million to participate, and not $5 million.
