If you have insider, read this article about Matthews. Pretty sweet imo. I only quoted a couple of paragraphs from the article, so I hope that doesn't go against board policies. If it's too much, mods feel free to take it out. My favorite part about the article is how Matthews, being an undrafted guy, is going to make double of John Wall. I'm mean, in a way, Matthews almost got lucky he went undrafted with that kind of money.
Yeah, I'm sure the player's union will have something to say about that in the next CBA. And the owners too. Having to give the 30th player in the draft a guaranteed deal, while the 31st has to earn a roster spot seems unfair. It's also the reason an early 2nd round pick is often a lot more valuable than a late 1st. And teams then not able to protect a guy they've developed, while superstars like Durant, Roy, Paul, Deron, etc making peanuts by comaprison for 4 years. That's a problem.
No doubt the Matthews' story is unique given the premise. But, IMO, you have to go back through the league before the draft was reduced to 2 rounds and before the current CBA went into effect before declaring Wesley truly "one of a kind." Up until the mid-80's the draft was 10 rounds! Then it was cut to 7 rounds, 3 rounds in 1988 and finally, in 1989, the draft was shortened to two rounds. So, just going back through Utah Jazz history, here are some of the siginifcant players who were picked in the 3rd round or later:
1982 - Mark Eaton (4th round)
1983 - Bobby Hansen (3rd round)
1985 - Delaney Rudd (4th round)
Off that list you have an all-star in Eaton and a starter in Hansen. Hansen really didn't start until his third year and he was picked #54 (fewer teams in 1983), so put a DQ by his name. Rudd was actually a decent PG for the Jazz for a few years. Unfortunately for him, Utah had some guy named Stockton, so he didn't get much playing time.
That leaves Mountain Man. Eaton started 32 games as a rookie, averaging 4 points, 6 rebounds and 3 blocks. Considering he didn't even start at UCLA and was working as an auto mechanic when drafted, I'd say his rise to fame is every bit the equal of Wesley Matthews' - maybe more impressive at this point. Just like Wesley, he became a starter mid-season (replacing Danny Schayes). Of course he didn't sign the big FA contract after that because the rules were different. Imagine if Eaton were in the same position in today's market. He'd be offered the full MLE by just about every team in the league.
I'm sure you can go through the draft history of many other teams and find guys drafted in the 3rd round or later who became starters their rookie seasons. So kudos to Wesley Matthews, but he's not the first to accomplish the feat - unless you've narrowed the search parameters quite a bit (must have been been a rookie only AFTER the current CBA was put in place).
