Now that the Bucs have inked up four of six draft picks for 2013, I thought it would be a good time to put on the ole’ mathematical hard hat and take a look at these numbers.

The new CBA doesn’t make these deals as exciting as previous years, but it’s still interesting to compare the figures.

Defensive tackle** Akeem Spence**, whose signing was announced today, has a signing bonus of $484,424. His base salary for 2013 is $405,000, in 2014 $495,000, in 2015 $585,000, and in 2016 $675,000.

Spence has a 2013 and a 2014 preseason split, meaning if he gets hurt during the preseason in those first two years, his salary will be reduced to $288,000, what’s called the ‘down-under amount,’ and divided over 17 weeks.

(Note – In a previous version of this article, the first-year split was stated incorrectly. These numbers aren’t split in half, as one might assume) For the second year, the split would be $318,000.

Spence’s 2014 base is credited. His deal works out to be $2.64 million.

Before going any further, the word ‘credited’ has to do with a player being on a 53-man roster for three or more regular or post-season games, in which he earns a credited season for that year. Players earning credited seasons are entitled to certain benefits under the new CBA, such as severance pay and savings plans.

Defensive end** William Gholston**, the other fourth-round pick for the Bucs, signed yesterday. His signing bonus is $400,544. He’ll make the same base salaries as Spence over the course of four years.

In fact, all of the players in the fourth through seventh rounds will. That’s part of the CBA. So again, in 2013 he’ll make $405,000, in 2014 $495,000, in 2015 $585,000, and in 2016 $675,000.

Rather than having a preseason split in 2013 like Spence, Gholston has a full-season split. It’d interesting that he has a full split while Spence doesn’t since Spence was drafted in the same round and most teams keep it pretty consistent.

Gholston has a preseason split in 2014 though and his 2014 base is credited. His deal totals just over $2.56 million.

Defensive end** Steven Means**, the Bucs’ fifth-round draft pick, signed Monday. His signing bonus is $191,752. He’ll make the same base salary as the others. He has a full split in 2013 and 2014. His 2014 base is credited. His total deal is worth about $2.35 million.

Running back** Mike James**, the Bucs’ sixth-round draft pick who also signed Monday, has a $103,152 signing bonus. Like Spence, Gholston, and Means, he’ll see his salary increase incrementally over four years.

James has a full split in 2013 and 2014 and his 2014 base is credited. The total value of his deal is worth $2.26 million.

**What’s Next?**

**Mike Glennon** should be the next in line to sign. Unlike the four previous players, his bases will likely be adjusted — at least that’s the way it appears. The Lions, Saints, and the Seahawks all adjusted bases for their third-round picks for years 2014-2016 (2013 base salaries remain the same).

An example of the type of contract you could expect for Glennon would be what Brian Winters got from the New York Jets. Winters was selected one spot ahead of Glennon at 72nd overall.

Winters has a signing bonus of $643,876. His bases are $405,000 in 2013, $529,000 in 2014, $618,000 in 2015, and $708,000 in 2016. His total deal is worth just over $2.9 million.

I didn’t see any workout bonuses for Winters. You may see one when second-round pick **Johnthan Banks** signs, as the Bucs did it last year with second rounder Lavonte David.
