I know it's an expensive lens as well as 2 stop slower than 70-200 f/2.8.
if I am not wrong ejm7 looking for a single lens which covers the landscape, portrait, & indoor sports photography. 70-200 f/2.8 is superior for indoor sports & portrait photography but, is it really enough wide for the landscape photography, as well as we can also maintain the faster shutter speed with the 28-300mm f/3.5-5.6 lens for the indoor sports photography with the higher ISO value. If we consider a full frame camera like 5d Mark ii, it is capable to maintain the low noise up-to ISO 2000.
And one more thing, Canon 70-200 f/2.8 L IS USM has a price tag at $2000+ and also add the another $1000 for the wide angle lens.

I bought the 5D Mark 3 with the 24-105mm f/4 L kit lens. Outstanding camera and lens. I assume since you mentioned "full frame" that you have the means to buy a more expensive camera. the mark three shoots 8 frames per second and has higher ISO settings if needed. f4 isn't the biggest aperture for sure but it's still pretty fast and remember this is "L" glass. 24-105mm is a great focal range for most photography though a tad short for sports. This is a great kit to shoot right out of the box and something you can build on as you go. Did i forget to mention the extraordinary auto-focus.

what will your budget support? 6D, is nice entry level FF.
Or if you have the budget the 5D MK3 has great reviews.1DX has more features than you may ever need and is priced accordingly
ONE lens for indoor sports and portraits, you might consider the 70-200 L for landscape I would lean towards an 18mm or less, might get by with 24-70L.
Can't help but wonder why you would sell all your glass?

I generally agree with these. Do not try to get one lens to cover all or you will be wasting your money moving to full frame.

You do not need a very fast lens for daytime or well-lit outdoor sports since you will probably not shoot wide open anyhow. An f/3.5 or f/4 zoom in that range (70-200) might save you some money and also handle portraits nicely.

For basketball and landscape the extra quality in an f/2, f/1.8 or f/1.4 normal and wide angle lens (not zoom) is where you might want to invest a little. A good 50mm should definitely be in the bag and if you want to do a lot of landscape, 28mm might be more useful than 35mm.

A faster lens will focus more accurately and quicker in dimmer light that a slower one.

Look at the 300 4.0. It wotks well with the 1.4 TE and doesn't cost an arm and a leg.

Keep in mind you can always get a quality used camera or lens through B &H, Adorama or KEH. I bought my 70-200mm 2.8 usm "L" lens with a matching 1.4 teleconverter and lens shade for right at $1,300. KEH offers lenses that range in condition from new to ugly and every thing between. My lens was rated excellent, No scratches, dents or blemishes on the body or glass that I could find. All but one of my lenses were purchased used, great savings and still great quality. Well worth the money I saved.

My take and I shoot sports, baseball currently despite the cold and windy days, football, basketball, soccer, wrestling in-doors of course. I shoot with a Canon 7D, and my "go to lens" is the Canon 70-200 2.8 lens. If you have the budget get the later version 70-200 2.8 version II. Without moving to the 1D series body the 7D is ideal for shooting sports.
I have used a 5D Mark ii to shoot sports, the frame rate is of course not as high as the 7D (8 frames per second) vs 5D Mark ii (2.8 frames per second), the focus on the 5D Mark ii is far less quicker and as crisp as the 7D.
If you still feel the need for a full frame camera body take a look at the Canon 1D Mark 2n, it was created after the 1D Mark ii of course but was created with the pro sports shooter in mind.
I also have a Canon 1DS Mark ii and it is a full frame camera I swapped and bartered with a local shop for this body. The LCD on the 1DS Mark ii is far smaller than the 7D. If you choose to move to the 1D series body be aware that the controls on the 1D series are far more in depth and far more customizable than the middle brands of the Canon line.
