Essentially, during OTA's, minicamps and training camp, the players receive "per diem expenses". It looks like they add up to about 5-10k during the offseason. In addition, roster and workout bonuses are payable on certain dates as negotiated into the individual contract.
This is from the prior CBA, I imagine the amounts increased some but are probably in line with these numbers:
XXXV. Offseason workouts:
Section 3. Each player shall receive at least the following amounts per day for any workouts or classroom instruction in which he participates pursuant to a Club's voluntary off-season workout program, provided the player fulfills the Club's reasonable off-season workout requirements: $90 during the 2002 League Year; $100 during the 2003-04 League Years; $110 for the 2005-06 League Years; and $120 for the 2007 League Year.
XXXV. Minicamps:
Section 3. Expenses: Any veteran player who attends a minicamp will receive meal allowances in accordance with Article XXXIX (Meal Allowance), Section 1 of this Agreement, plus all travel expenses to and from the camp, plus “per diem” payments at the rate provided in Article XXXVII (Salaries), Section 4 of this Agreement. In addition, the Club will provide housing at minicamps for players coming from out‑of‑town.
Article XXXVII. Pre-season training camps:
Section 3. Rookie Per Diem: During the term of this Agreement, a rookie player will receive "per diem" payments at the rate of $725 per week in the 2002-03 League Years, $750 per week in the 2004 League Year, $775 per week in the 2005-06 League Years, and $800 per week in the 2007 League Year, commencing with the first day of preseason training camp and ending one week prior to the Club's first regular season game.
