Add Plumlee to first-round watchlist

The Boston Celtics hosted another pre-draft workout on Tuesday and one of the invitees -- Northeastern guard Jon Lee (who raised eyebrows with what's believed to be a record-breaking performance in the team's three-minute sprint drill at the end of workouts last week by running 29 ½ court lengths -- Tweeted that the session included Duke center Mason Plumlee, Miami center Reggie Johnson, and Belmont guard Ian Clark.

Lee, Johnson, and Clark fall into the growing list of players projected to be selected in the second round (or undrafted) that the team has worked out, but 7-foot Plumlee is a mid-first round prospect and the type of big man the Celtics could potentially have their eyes on with their lone current pick at No. 16 (Plumlee was pegged at No. 20 in Chad Ford's latest mock, which also makes you wonder if the C's might consider shuffling back a couple spots if they could pick up a second-round selection in the process).

Plumlee is 15th on ESPN's Top 100 big board and the fourth-ranked center, behind Nerlens Noel, Alex Len, and Steven Adams (who worked out for Boston last month).

In other draft-related news: The Journal Times of Rancine, Wisc. addressed the rumored Celtics' promise to German point guard Dennis Schroeder:

Schröder’s agent, Alex Saratsis, tried to squelch the Schröder “promise” as well.

“I don’t know where that came from,” Saratsis said. “I don’t know anything about that.”

Rumors began to circulate at last month’s pre-draft camp in Chicago that an NBA team “promised” it would select Schröder if he entered the draft. The team most frequently associated with the “promise” was Boston. The Celtics have the 16th overall pick.

Yet, even if the Celtics made a guarantee to draft the talented and athletic Schröder, there aren’t any guarantees he’ll even be on the board for them. That’s because several teams drafting in front of Boston have more than a passing interest in the 19-year-old German, including the Milwaukee Bucks, who pick one spot ahead of the Celtics.
