Ah, the irreplaceable 4 points of Greg Lewis. There's no end to the list of not-good players that get hurt and are replaced by not-good players often out of position.
I don't think Lewis would have been a "not good player" without the injury.
Last year he averaged 5.3 pts, 4.5 rbs and 0.9 blocks in 23.8 minutes. Even as the walking wounded, he still improved upon his "per 40 minute" numbers for rebounds and blocks, and his points only slipped a little. If you just took his numbers for this year, and allowed him to average 28 minutes per game, he'd be at 5.3 pts/6.7 rbs/1.3 blocks.... if you took away the knee injury and ankle cyst and allowed him to practice, those numbers definitely would have been better.
If he had been fully healthy all season, he may have been a 10 pts/9 rbs/2 blocks player as a senior.
Can't knock the kid - he's been dealt a **** hand, and he's playing it out. I'm sure this is not the scenario he envisioned for himself as a 5th year senior.
