BOSTON (CBS) — Friday was an extremely busy day for the New England Patriots’ front office. Yet by the end of it, they only drafted one player.

It was a day that began with a trade, when the Patriots sent the 95th overall pick (a third-rounder) to San Francisco. In return, the Patriots received tackle Trent Brown and the 143rd overall pick (a fifth-rounder).

As it turned out, that trade would be the first of many.

Heading into the second day of the draft, the Patriots were slated to pick at No. 43 overall, No. 63 overall, and No. 95 overall. But a series of trades led to the Patriots picking at none of those spots. Instead, on their third trade of Friday night, they moved up to select Florida cornerback Duke Dawson out of Florida.

In the midst of all the trading, the actual return for Jimmy Garoppolo got a bit muddied. Originally, the Patriots acquired the No. 43 overall pick from the 49ers in exchange for Garoppolo. But that pick got traded, and then traded again, so the actual return isn’t quite as simple as being one player.

Here’s a play-by-play of how the Patriots got to that point on a busy Friday.

Step One
Entered the day with:
No. 43 overall
No. 63 overall
No. 95 overall

Step Two
Traded No. 95 (third round) for Trent Brown and No. 143 (fifth round)

Step Three
Traded No. 43 overall (second round, Garoppolo pick) to Detroit in exchange for No. 51 overall (second round) and No. 117 overall (fourth round)

Step Four
Traded No. 51 (second round, acquired from Detroit) for No. 105 (fourth round) overall and 2019 second-round pick from Chicago

Step Five
Traded No. 63 overall (second round, Patriots’ own pick) and No. 117 overall (fourth round, acquired from Detroit) to Tampa Bay for No. 56 overall (second round)

Step Six
Used the No. 56 overall pick on Duke Dawson, cornerback out of Florida

That’s a whole lot of maneuvering just to essentially drop from No. 43 to No. 56.

To sum, here’s everything the Patriots traded away, and everything they received in return on Friday.

No. 43 overall (second round)
No. 51 overall (second round)
No. 63 overall (second round)
No. 95 overall (third round)
No. 117 overall (fourth round)

T Trent Brown
CB Duke Dawson
No. 105 overall (fourth round)
No. 143 overall (fifth round)
2019 second-round pick (Chicago)

And that put a wrap on their Friday night activity. But Saturday promises to be busy, too, as they enter the day with five picks in rounds four through seven.
