To be fair, Lee didn't make that tackle due to injuries. In 2015 the Steelers lost their Kicker for the year when making a tackle, and this year their kicker got drilled in the head making a tackle. It's stupid for a punter/kicker to try and tackle in preseason, just walk off the field and stay healthy.
Summary: The former Wake Forest transfer was not even on my NBA Draft radar prior to the NCAA Tournament, but due to VCU's magical run to the Final Four, he suddenly drew a lot of interest and deservedly so. He has good size and a talented enough inside/outside game to draw second-round looks. If he goes undrafted, he will certainly get a chance to prove his worth in the summer league and in some team's training camp.
Player Comparison: Brian Cook. A below-average athlete by NBA standards, Cook has stuck around in the league due to his ability to step out and knock down jump shots. Skeen has that weapon in his arsenal and also the strength to overcome his lack of size. I would not expect Skeen to be to anything more than a seldom-used role player at the next level like Cook.
