Brokefish, no doubt indoor courts would be nothing but a positive. My main point was that playing indoors isn't a valid excuse for losing to Baylor, who has to drive an hour and a half to the nearest indoor courts to Waco. Actually I have never thought about this but the Bryan courts may be closer to Waco than Ennis!
Teams from the north not being as competitive has more to do with the weather than with playing indoors. When you spend October to March playing on a different surface, in a climate-controlled environment (most importantly with no wind), you're going to suffer intially when you first have to play outside. That's why Ohio State couldn't wait to call the match off in Waco this year and why t.u. women beat a much stronger Northwestern team who was just beginning their outdoor season. Trust me, as a guy that took years to get used to the Texas heat, a beautiful 85 degree C.S. spring day can seem like the Sahara to a team from Illinois or Ohio who hasn't seen sun in months and hasn't seen 90% humidity...ever.
Again, there are a ton of positives from having indoor courts, most of them you mentioned. I just think that we ALREADY have a huge advantage over northern teams (and to be clear, that's basically every team north of the southernmost states, even Oklahoma, etc., and obviously the advantage gets bigger over very northern schools who can't practice outdoors at all until April).
I do feel that we would have just as much of a disadvantage going up north in February and playing them indoors, but I think that it would be only slightly mitigated by having our own indoor courts. Sure, if would make us slightly more accustomed to them and it would definitely help somewhat, but we're still not going to spend the bulk of our time practicing indoors. I mean, if Denton schedules a February match at Ohio State, he would definitely spend a few days practicing indoors regardless of the weather, but then it's right back to the outdoors before the next week's home match with whomever.
The point is, we're still not going to practice indoors EVERY DAY or nearly every day from October to April like Ohio State and Notre Dame do, so they are always going to have an advantage indoors, just like we will always have an advantage outdoors and in the heat...and the season ends (typically) outdoors and in the heat, which is one of the many reasons why there has only been one men's tennis championship team (Illinois 2003) from a school that does not touch the southern border of the US in the last FIFTY years and only three ever!
Yes, if we have money laying around, let's build indoor courts and clay courts and every other possible advantage we can think of...but right now we don't appear to have money laying around and all I'm saying is that these facilities aren't making or breaking us. Don't resurface a few of the rec courts and let them get fast or practice at Bryan more - if they are so fast, then that will help offset the big change when we do have to play indoors, and by the way indoor surfaces vary just as much as outdoors and though they are typically fast, yes, there are schools that resurface often and at high texture and do have "slow" indoor courts.
Summary: Keep recruiting and developing great players but do an even better job at it. That's how we're going to win a national championship. It's a lot cheaper and more realistic to land another Krajicek or Pollock in the next 2 years than it is to think we're going to get a multimillion dollar facility for a non revenue-generating sport in a failing economy. Plus the players actually help us win.
We're RIGHT there on the edge of being great - What if Spencer had stayed and we had landed Jenkins? I think we'd still be playing!
