would it be possible for that player to sue me for Defamation or Intentional Infliction of Emotional Distress?
No. All the examples you mention are statements of opinion. Only statements of fact are actionable under defamation law.
For instance, the meaning of being "f****** awful" or "garbage" are too unclear, subjective, vague, and/or hyperbole. That kind of statements are not susceptible of corroboration because there is no objective standard to prove or disprove them. As such, they contain little-to-no "information" for others to dissociate from the referred individual.
The standard for awarding damages in counts of Intentional Infliction of Emotional Distress (IIED) is much higher than targeting someone in the way you mention. Counts of IIED are intended for situations involving severe suffering, perhaps comparable to torture. Many lawyers waste their clients' money by pleading IIED despite the well known fact that counts of IIED typically fail the standard of severity for the law intends to remedy.
Courts are selectively less tolerant to vulgarity if the target thereof is an individual in a situation of heightened sensitivity, or a privileged individual such as a judge or a king, notwithstanding that sanctioning the vulgarity is likelier to bring more attention thereto in the case of public figures.
As an example, in Morris v. Schnoor (May 29, 2014) (see section "IV. Appellate Sanctions"), the Michigan Court of Appeals sanctioned attorney David Charron for bashing a judge with statements such as "When the judiciary acts as the b---- for complainant, we get rulings like this" (I'm adding dashes here). As was very obvious and predictable, the sanction gathered the attention of the media to the attorney's statement of opinion. Other than that, in many jurisdictions it is extremely unlikely that calling a basketball player or an average civilian the b-word would prompt a court to address the vulgarity at all.
