Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.
http://cdn.espn.com/core/format/modules/head/i18n?…e=ext&build=0.347.10.1
http://a.espncdn.com/redesign/0.347.10/js/espn-critical-mobile.js
Optimize CSS Delivery of the following:
http://a.espncdn.com/redesign/0.347.10/css/shell-mobile.css
http://a.espncdn.com/redesign/0.347.10/css/page.css
http://a.espncdn.com/redesign/0.347.10/css/one-feed-v1.css
Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 38% of the final above-the-fold content could be rendered with the full HTML response.
Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
http://aglobal.go.com/stat/cto-espn.js (expiration not specified)
http://secure-us.imrworldwide.com/v60.js (expiration not specified)
http://fan.api.espn.com/apis/v2/recommendations/po…s=true&displayNow=true (73 seconds)

Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 9KiB (64% reduction).
Compressing http://cdn.espn.com/core/format/modules/head/i18n?…e=ext&build=0.347.10.1 could save 9KiB (64% reduction).
Minify HTML

Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 1.2KiB (35% reduction).
Minifying http://secure-us.imrworldwide.com/storageframe.html could save 1.2KiB (35% reduction) after compression.
Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 634B (16% reduction).
Minifying http://a.espncdn.com/redesign/0.347.10/node_module…lazysizes/lazysizes.js could save 634B (16% reduction) after compression.
